Use pythagorean theorem to find the bottom side of the left triangle.
12^2+b^2=15^2
144+b^2= 225
b^2= 81
b=9
you will then subtract 9 from 25 to get 16
area from the triangle on the right
A=(1/2)16*12
A= 96 in^2
then for the triangle on the right
A= (1/2)12*9
A= 54 in^2
then add the two areas together
Total Area= 150 in^2
Answer:
Step-by-step explanation:
1. multiply by 2
2. multiply by 4 -> 96
3. by 3 ->120
Answer:
for the first one: y=1x and second one: y=-2
Slope intercept form is y = -2x + 14
Step-by-step explanation:
- Step 1: The original equation is 4x + 2y = 14.
- Step 2: Rearrange so that x is first in the right hand side of the equation.
⇒ 2y = - 4x + 14
- Step 3: Subtract 4x from both sides of the equation.
⇒ 2y = 14 - 4x
- Step 4: Divide both sides of the equation by 2 so that coefficient of y is 1.
⇒ y = - 2x + 7
This is the slope intercept form y = mx + b
The answer is 4:15. (Also NEVER click on links with the bit . ly thing)
