Answer:

4 x + -43

Step-by-step explanation:

Simplify the following:

7 (x - 4) - 3 (x + 5)

Hint: | Distribute 7 over x - 4.

7 (x - 4) = 7 x - 28:

7 x - 28 - 3 (x + 5)

Hint: | Distribute -3 over x + 5.

-3 (x + 5) = -3 x - 15:

7 x + -3 x - 15 - 28

Hint: | Group like terms in 7 x - 3 x - 28 - 15.

Grouping like terms, 7 x - 3 x - 28 - 15 = (7 x - 3 x) + (-28 - 15):

(7 x - 3 x) + (-28 - 15)

Hint: | Combine like terms in 7 x - 3 x.

7 x - 3 x = 4 x:

4 x + (-28 - 15)

Hint: | Evaluate -28 - 15.

-28 - 15 = -43:

Answer: 4 x + -43

Answer:

4x – 43

Step-by-step explanation:

[tex]\bf Step-by-step~explanation:[/tex]

[tex]\bf Step~1:[/tex]

To solve this, we have to simplify these numbers by adding like terms.

[tex]42x^2+34-8-12\\\\(34-8=26, 26-12=14)\\\\42x^2+14\\[/tex]

[tex]\bf Step~2:[/tex]

Next, we factor our expression. To do so, we look for the greatest common factor of 42 and 14, which is 14. We know that because 42 divided by 14 is 3.

[tex]\frac{42}{14} =3[/tex]

[tex]\boxed{ \bf Our~final~answer: 14(3x^2 + 1)}[/tex]

Answer:  d) 6   e) 10     g) 900

Step-by-step explanation:

d) [tex]\sqrt{9610} = 98.0306[/tex]

98² = 9604

9610 - 9604 = 6

e) [tex]\sqrt{2906}=53.9073[/tex]

54² = 2916

2916 - 2906 = 10

g)              10            12          15

                 ∧             ∧            ∧

               2·5         2·2·3       3·5

The Perfect square is: 2² · 5² · 3² = 30²

30² = 900

Answer:

[tex]Y^4[/tex]

Step-by-step explanation:

Given:

Y to the fourth Power

Required

Express using mathematical expression

In mathematics;

To the nth power means raise to the power of n

In this case;

to the fourth Power means raise to the power of 4

Hence;

Y to the fourth Power = Y raise to the power of 4

And this can be represented mathematically as:

[tex]Y^4[/tex]

Step-by-step explanation:

Answer:

a = 16

Step-by-step explanation:

6 = a/4 + 2

Switch sides.

a/4 + 2 = 6

Subtract 2 from both sides.

a/4 = 4

Multiply both sides by 4.

a = 16

Answer:

y=7x-27

Step-by-step explanation:

The equation of a line is given by y=mx+C where m is the gradient of the line or slope and c is the intercept on your axis. according to your question, you are given two point on (3,-6) and (5,8). so we can get the gradient m= Y2-Y1/X2-X1= gradient. so Y1= -6, Y2=8 , X1=3, X2=5

slope= 8-(-6)/5-3=14/2=7. so m=7....so the equation of line can be written in form y=7x+C. but we need to find C. C can be gotten from where the line passes through (3,-6) that is when x=3, y=-6. so we can find C from that point. -6=7(3)+C..so we have -6=21+C. C=-6-21=-27

so the equation of the line is y=7x-27

Answer:

17.

Step-by-step explanation:

We know that NP = NO + NP because all the points are on the same line.

So 2x = 10 + (x + 7),

x = 17.

Answer: Its 8

Step-by-step explanation:

Answer:

Consecutive integers:

x

(x+1)

(x+2)

Now your equation is given by sum of the first and twice the third is equal to four times the second decreased by five:

x+2(x+2) = 4(x+1)-5

Step-by-step explanation:

Answer:

10, 11 and 12.

Step-by-step explanation:

Let the integers be x, x+1 and x+2. Then:

x + x+2 = 22

2x = 22 - 2 = 20

x = 20/2

x = 10.

Answer:

p = 7

Step-by-step explanation:

Look at the picture hope this helps!

18.84 rounded to the nearest tenth is 18.8.

Rounding to place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

We can see that round a number to the nearest tenth, we need to look at the digit in the hundredth place. In this case, the number is 18.84.

Therefore, digit in the hundredth place is 4.

If the digit in the hundredth place is less than 5, we round down to the previous tenth. If it is 5 or greater, we round up to the next tenth.

Since 4 is less than 5, we round down. Therefore, 18.84 rounded to the nearest tenth is 18.8.

Answer:

G could be at either 14 or at -6.

Step-by-step explanation:

i'm gonna assume that "leg" refers to length of the triangle, so comment if you think it is wrong.

Now when it comes to a right-angled triangle, the pythagoras theorem formula can be used.

Using algebra,

let the missing length be X.

By pythagoras theorem,

5² = 3² + X²

5² - 3² = X²

X² = 5² - 3²

X = sq root ( 5² - 3² )

= 4 m

Therefore, the length of the missing leg is 4m .

For the first pic:

S= (3,4)

U= (-4,0)

V= (1,-2)

T= (-2,-3.5)

I hope this helped! Sorry if you get this wrong! :)
