Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.

Given area of a rectangle: 7x^2+57x+8 <br> Find Perimeter:
Sever21 [200]

Answer:

Perimeter of the rectangle is 16x+18 units.

Step-by-step explanation:

The area of rectangle is

7x^2+57x+8

First we have to find the factor form of above expression.

Splitting the middle term, we get

7x^2+56x+x+8

7x(x+8)+1(x+8)

(x+8)(7x+1)

Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).

Perimeter of a rectangle is

Perimeter=2(l+b)

Perimeter=2[(x+8)+(7x+1)]

Perimeter=2[8x+9]

Perimeter=16x+18

Therefore, the perimeter of the rectangle is 16x+18 units.

Simplify completely. Leave your answer in exponential form:
stich3 [128]

Answer:

{2}^{3}  \times  {4}^{3}  \times 9

Step-by-step explanation:

Using the division rule when dealing with exponents

\frac{b {}^{h} }{b {}^{j} }  = b {}^{h - j}

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.

so using that we are going to do 2, 4 and 9

\frac{2 {}^{8} }{ {2}^{5} }  =  {2}^{8 - 5 = 3 \:  \:  \:  \:  \: 2 {}^{3} }

\frac{ {4}^{4} }{ {4}^{1} }  =  {4}^{4 - 1}  \:  \:  \:  {4}^{3}

\frac{9 {}^{9} }{ {9}^{8} }  =  {9}^{9 - 8}  = 9 {}^{1}

Combine all the terms and we get

{2}^{3} \times 4 {}^{3}  \times  {9}

Is 8 a solution to the equation below? Yes or No?<br><br><br> 3(x - 2) + 4 = 22
Simora [160]

To see if 8 is the solution to the equation,  3 (x - 2) + 4 = 22, you must replace x with 8 and solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS . If the sides are equal to each other then 8 IS a solution.

3(8 - 2) + 4 = 22

Parentheses...

3(8 - 2) + 4 = 22

8 - 2 <<<In the parentheses so you must solve first

6

so...

3(6) + 4 = 22

Multiplication...

3(6) + 4 = 22

3 * 6

18

so..

18 + 4 = 22

Addition...

18 + 4 = 22

18 + 4

22

so...

22 = 22

Are they equal to each other? YES!!!

8 is a solution to the equation 3 (x - 2) + 4 = 22

Hope this helped!
