2. The floor plan for a rectangular building states that the length of the building is to be 8 meters more than 3 times its width . If the floor area is to be 256 square meters, what must be the length and width of the building?

Area of a rectangle = Length × Width

Length of the building is to be 8 meters more than times its width.

= Length = 3W + 8

Area = 256m²

Hence:

256 =( 3W + 8 )× W

256 = 3W² + 8W

= 3W² + 8W - 256

Factorise

= 3W(W - 8) + 32(W - 8)

= (3W + 32) ( W - 8)

W - 8 = 0

W = Width = 8m

Length = 3W + 8

Length = 3(8) + 8

= 24 + 8

= 32m.

D. 32 meters long and 8 meters wide

3. The area of the dining room is 130 square units. If the width is 3 meter less than its length what is the width

of the room?

A. 10 units

B. 11 units

C 12 units

D. 13 units

Area = Length × Width

The width is 3 meter less than its length

W = L - 3

Area = 130 square units

Hence:

130 = L (L - 3)

130 = L² - 3L

L² - 3L - 130

= L² + 10L - 13L - 130

= L(L + 10) - 13(L + 10)

= (L - 13) (L + 10)

L - 13 = 0

L = Length = 13 units

L + 10 = 0

L = -10 units.

W = L - 3

L = 13 units

W = 13 - 3

W = 10 units

Therefore, the width of the room is 10 units

A. 10 units

4. One of the factors of 2b² + 15b-50 is b + 10. What is the other factor?

A.2b - 10

B. 2b -5

C. 2b +5

D. 2b + 10

2b² + 15b -50

One of the factors is b +10.

We factorise

2b² + 15b - 50

= 2b² + 20b - 5b - 50

= 2b(b + 10) - 5(b + 10)

= (2b - 5) (b + 10)

The other factor is 2b - 5

B. 2b -5

5. The area of the nachos is 15x² - 10x square centimeters. If the base is 5x centimeters, which is the length of

the height?

A. 3x - 2 cm.

B. 3x + 2 cm

C. 6x-4 cm

D. 6x + 4 cm

Nachos are triangular in shape

Area of a triangle = 1/2 × Base × height

A = 1/2 bh

A = bh/2

2A = bh

h = 2A/b

The area of the nachos is 15x - 10x square centimeters. If the base is 5x centimeters,

h = 2(15x² - 10x)/5x

h = 30x² - 20x/5x

h = 30x²/5x - 20x/5x

= 6x - 4 cm

the length of the height is:

C. 6x - 4 cm

Answer:

by BPT it will be solved

Step-by-step explanation:

CQ/QA=CP/PD

x+2/x=5x+4/3x

by cross multiplication

answer will be 1

Parallel sides are sides that are equidistant from one another. The value of x is 1

Given that:

[tex]CQ = x + 2\\QA = x\\CP = 5x + 4\\PD = 3x[/tex]

Since:

QR & AB are parallel, and RP & BD are parallel.

Then by theorem of similarities:

[tex]\frac{CQ}{QA} = \frac{CP}{PD}[/tex]

This gives:

[tex]\frac{x+2}{x} = \frac{5x + 4}{3x}[/tex]

Multiply both sides by 3x

[tex]3x \times \frac{x+2}{x} = \frac{5x + 4}{3x} \times 3x[/tex]

[tex]3 \times (x+2) = 5x + 4[/tex]

Open bracket

[tex]3x+6 = 5x + 4[/tex]

Collect like terms

[tex]5x - 3x = 6 -4[/tex]

[tex]2x = 2[/tex]

Divide both sides by 2

[tex]x = 1[/tex]

Answer:

369600 feet per hour

Step-by-step explanation:

1m = 5280ft

5280 x 70 = 369600

Answer:

369,600 feet per hour

Step-by-step explanation:

1 mile = 5,280 feet

70 mph (cheetah's speed) x 5,280 feet (feet in 1 mile) = 369,600 feet (cheetah's speed in feet)

The answer is 405 because if you multiply 3 and 135 that would lead you to your answer.

We know that the diagonals of a square bisect each other which results in the formation of 4 - 90° angles . Which means ZX = 2 × WT . Then ,

= ZX = 2 × 6

= ZX = 12 ( ZX is a diagonal )

Side XY =

XY = √2 d/2

XY = √2 . 12/2

XY = 8.48528

m∠WTZ = 90° ( as the diagonals of a square intersect to form a complete angle ( 360° ) which is divided into four equal parts , each part being 90° )

m∠WTZ = 90°

m∠WYX = 45° ( WYX is half of one of the interior angles in this square which will mean it will be equal to 45° )

Therefore , m∠WYX = 45°

ZX = 12

XY = 8.48528

m∠WTZ = 90°

m∠WYX = 45°

Answer:

CE=108

Step-by-step explanation:

*I don't have my phone with me so I can't add a picture of what I drew*

First, draw a line. On one end, write C. On the other end, write E. In the middle of them, write D. The question states that CE=6x, so on the bottom of the line, write 6x. On top on the first half write 4x+8 (between C and D). On the other half between D and E write 28.

According the the information we have been given and the diagram we made, CD+DE=CE. Hence, (4x+8)+28=6x

(4x+8)+28=6x (subtract four from both sides)

8+28=6x-4x (combine like terms)

36=2x (divide two from both sides)

x=18

Now, substitute 18 for x in 6x (CE=6x)

CE=6(18)

CE=108

Answer:

[tex]x = \frac{21}{2}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x − 3(x+9) + 10 = 4

5x + (−3)(x) + (−3)(9) + 10 = 4 (Distribute)

5x + −3x + −27 + 10 = 4

(5x+−3x) + (−27+10) = 4 (Combine Like Terms)

2x + −17 = 4

2x − 17 = 4

Step 2: Add 17 to both sides.

2x − 17 + 17 = 4 + 17

2x = 21

Step 3: Divide both sides by 2.

[tex]\frac{2x}{2} = \frac{21}{2}[/tex]

[tex]x =\frac{21}{2}[/tex]

Answer:

No, because not all corresponding angles are congruent.

Step-by-step explanation:

In order for two triangles to be similar you must have that you know at least 2 corresponding angles are congruent which would also imply the third set of angles are also congruent. You can also tell if two triangles are similar based on their corresponding sides being proportional. Without even checking the proportionally part of corresponding sides, I see the 3 angles in the first triangle do not have the same measurement as the one in the second triangle. Therefore, the triangles cannot possibly by similar.

Hope this helped you love.

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)
