He used 647.75 square meters of wrapping paper to wrap the gift.
According to the question,
We have the following information:
We have a figure made of 2 same triangles and 3 rectangles with different measurements.
Area of triangle = 1/2 * base*height
Area of triangle = (1*7*14)/2
Area of triangle = 49 [tex]m^{2}[/tex]
Now, the area of another same triangle will also be 49 [tex]m^{2}[/tex].
Now, we have:
Area of upper rectangle = length*breadth
Area of upper rectangle = 15*14
Area of upper rectangle = 210 [tex]m^{2}[/tex]
Area of middle rectangle = length*breadth
Area of middle rectangle = 15*7
Area of middle rectangle = 105 [tex]m^{2}[/tex]
Area of lower rectangle = length*breadth
Area of lower rectangle = 15.65*15
Area of lower rectangle = 234.75 [tex]m^{2}[/tex]
Now, the area of the wrapping paper will be the sum of all of these areas.
Area of paper = Area of 2 triangles + area of upper rectangle + area of middle rectangle + area of lower rectangle
Area of paper = 49+49+210+105+234.75
Area of paper = 647.75 [tex]m^{2}[/tex]
Hence, the area of wrapping paper is 647.75 [tex]m^{2}[/tex].

Answer:
x = 4 , x = 2.4
Step-by-step explanation:
[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5
multiply through by (x - 2)(x - 3)
4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)
4x - 12 + 3x - 6 = 5(x² - 5x + 6)
7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )
0 = 5x² - 32x + 48
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 48 = 240 and sum = - 32
the factors are - 20 and - 12
use these factors to split the x- term
0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )
0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term
0 = (x - 4)(5x - 12)
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4

0 < - 27
Step-by-step explanation:
1. Distribute
3x + 6 < 3(x-7)
3x + 6 < 3x - 21
2. Subtract 6 from both sides
3x + 6 < 3x - 21
3x + 6 - 6 < 3x - 21 - 6
3. Simplify
subtract
3x + 6 - 6 < 3x - 21 - 6
3x < 3x - 21 - 6
subtract
3x < 3x - 21 - 6
3x < 3x - 27
4. Subtract 3x from both sides
3x < 3x - 27
3x - 3x < 3x - 27 - 3x
5. Simplify
combine like terms
3x - 3x < 3x - 27 - 3x
0 < 3x - 27 - 3x
0 < 3x - 27 - 3x
0 < - 27

A measure of speed is the rate at which something is happening, moving, or moving swiftly. The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed.From graph Journey Started at 2PM
on 3PM James covered 20 km
Hence Speed = (20 - 0)/(3 -2) = 20 km/hr
outward journey Speed = 20 km/hr
Now outward Distance = 45 km
Time taken = 45/20 = 2 hr 15 min
Hence reached at 4 : 15 PM

Similarity Theorems
Triangles ABG and DCB are similar by the AA similarity postulate
"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"
The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.
On the other side, angles DBC and AGB are congruent also because they are both right angles.
With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

The given equation is

We want to test if x = 6 is a solution. We would substitute x = 6 into the equation. We have
5(6 - 3) = 6 + 13?
5(3) = 6 + 13?
15 = 19?
Since both sides of the equation is not equal, then
x = 6 is not a solution of the equation

Step by step
First I put our equation into y intercept form
2y = -1x + 7
Divide both sides by 2 to isolate y
2/2 y = -1/2x + 7/2
y = -1/2x + 3 1/2
Now we fill in your chart
From this we see the y intercept is at 3 1/2, so at (0, 3 1/2) is our coordinate on the y axis.
Enter this on your chart at 0x.
From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0
3 1/2 + -1/2 = 3, (1, 3)
3 + -1/2 = 2 1/2 (2, 2 1/2)
2 1/2 + -1/2= 2 (3, 2)
Moving left from 0
3 1/2 - -1/2 = 4 (-1, 4)
