−6&gt;−30−4x<br> help please
nikklg [1K]

from both sides of the equation.

Answer:

Apply the distributive property.

6 ⋅ 5 + 6 (-3x) = -4 x - 12

Multiply

6 by 5 . 30 + 6 (-3 x) = - 4 x - 12

Multiply

− 3 by 6 . 30 - 18 x = - 4 x - 12

Add

4 x to both sides of the equation.

30 - 18 x + 4 x = - 12

Add

− 18 x and 4 x . 30 - 14 x = - 12

Subtract

30

from both sides of the equation.

- 14 x = - 12 - 30

Subtract

30 from

− 12 . - 14 x = - 42

x = 3

Answer:

60m^2

Step-by-step explanation:

First, find the area of the square as it the missing piece wasn't missing.

    8 x 9 = 72m^2

Then, find the area of the missing section.

    3 x 4 = 12m^2

Finally, subtract 12m^2 from 72m^2 and you get 60m^2

I NEED HELP PLEASE! :)<br> thanks!
torisob [31]

Since ΔABC ~ ΔEDC, ∠B = ∠D.

Since both triangles appear to be similar, the corresponding angles are the same, and corresponding sides are the same or have the same ratio.

We can write an equation to resemble the problem:

8x + 16 = 120

Solve for x.

8x + 16 = 120

~Subtract 16 to both sides

8x + 16 - 16 = 120 - 16

~Simplify

8x = 104

~Divide 8 to both sides

8x/8 = 104/8

~Simplify

x = 13

Therefore, the answer is 13.

Best of Luck!
