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)

Answer:

324 ft^2

Step-by-step explanation:

ok so to calculate the area its A = wl (width x length)

9 x 12 = 108 ft^2

buuuuuut since we have 3 walls were going to have to multiply it by three as cuz 108 ft^2 is the outcome of one wall

108 ft x 3 = 324 ft^2

4(2x+10) = 10(x+3)
8x + 40 = 10x + 30
2x = 10
  x = 5

AE =2x+10 = 2(5) +10 = 20

The ratio of three angle are 3:4:5 <br>what is the highest angle of the triangle??
SCORPION-xisa [38]
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x. 
we can suggest the following equation:
3x+4x+5x=180

12x=180
x=180/12
x=15

The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: the highest angle would measure 75º.

From his home, Clayton would have to walk 4 miles north to get to his friend Miki's house and 1 mile east to get to his friend D
iren2701 [21]
The houses form a right triangle. Using a²+b²=c² you will find that the distance from Clayton’s house to Danny’s would be 4.1 miles. Adding it all up, the distance would be 9.1 miles of walking.
