Answer:

b. 36

Step-by-step explanation:

You have to use Pythagorean theorem. A squared + b squared = c squared.

a=12 12^2 (12 squared)= 144

b=9 9^2 (9 squared)= 81

144+81=225

Then you find the square root of 225 which is 15. Since you have the length for side c.

12+9+15=36

Answer:

Step-by-step explanation

You would first have to find the hypotenuse to do that you would follow the formula c = √a²+b², giving you 15.

Next you would add all the sides P = a+b+c, giving you 36.

The perimeter of this triangle would be 36.

Brett painted three walls. Each wall was 9 ft tall and 12 ft long. How much wall area did he paint

julsineya [31]

Answer:

First we need to calculate the are of each wall, since we alredy knew the length (l) and the width (w) which is the height of the wall in this case:

A = wl = 9 . 12 = 108 (ft²)

We also know that he painted 3 walls, we need to multiply our first result by 3, in other words, the area of wall that Brett painted is the sum of the area of three walls: 108 . 3 = 324 (ft²)

Solve for y. 6x-4y=-16

musickatia [10]

$y = \frac{6}{4} x + 4$

Explanation:
1. you subtract 6x to get 4y alone. which will get you -4y=-6x-16
2. then you divide everything by -4 to get y completely alone.
This will get you the answer of y=6/4y+4
