Answer:

You subtract 9 from both sides

Step-by-step explanation:

You have to get the variable by itself to solve so you subract 9 by 9 and they cancel each other out. Then you do -12-9 and since they are both negative you get get -21

Them you have your answer m=-21, you can check this by plugging m inot the equation

If you are solving for M

You would subtract 9

m + 9 = -12

- 9 - 9

M = -21

Answer:

5x = 5(10) = 50 inches

Step-by-step explanation:

Let x = length of shorter piece then

5x = length of the longer piece

x + 5x = 60

6x = 60

x = 10 inches (shorter piece)

Longer piece:

5x = 5(10) = 50 inches

What is the area of this figure? 49.5 in² 66.5 in² 84 in² 91 in²

zubka84 [21]

The given figure can be divided in two parts 1) Square with side 7 in 2) A right triangle with base 12 in and height 7 in.

1) Area of square = $side^{2}$

Side of the square is 7 in.

Area = $7^{2} =49in^{2}$

2) Area of triangle = $\frac{1}{2} .base . height$

Area of triangle = $\frac{1}{2} (12)(7) =42in^{2}$

Area of polygon= Area of square+ Area of triangle

Area of polygon = 49+42 =91 square in.

Area = $91in^{2}$

Prove algebraically that (m + 2)2 – m 2 – 12 is always a multiple of 4

Julli [10]

Answer:

$(m + 2)^{2} - m^{2} - 12 = 4(m - 2)$

Step-by-step explanation:

Step 1:

Write the expression

$(m+2)^{2} - m^{2} - 12$

Step 2: Expand $(m + 2)^{2}$

$(m+2)^{2} - m^{2} - 12\\(m+2)(m+2) - m^{2} - 12\\m^{2} + 2m + 2m + 4 - m^{2} - 12$

Step 3: Collect similar terms

$m^{2} - m^{2} + 4m + 4 - 12\\4m - 8$

Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.

$Therefore\\4m - 8 = 4(m - 2)\\Hence,\\(m+2)^{2} - m^{2} - 12 is a multiply of 4 because the expression is equal to 4(m-2)$
