Answer:
39 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
Let:
base = b = 4 ft
height = h = 3 ft
Solve for the area of the triangle:
A = 1/2(4)(3)
A = 2 * 3
A = 6 ft²
Area of a rectangle = bh
Let:
base = b = 9 ft
height = h = 5 ft
Solve for the area of the rectangle:
A = (9)(5)
A = 9 * 5
A = 45 ft²
Subtract the area of the triangle from the area of the rectangle:
45 - 6 = 39 ft²
39 ft² is your answer.

Answer:
30 x 4 + 4 x 4 and 4 x 4 + 4 x 30
Step-by-step explanation:
A characteristics of an exponential decay function is it has a constant term that is lesser than 1, this is because when you raise it a number that is lesser than 1 to higher values the result will be lesser and lesser, that is why it is called decay function. so the decay functions are a. f(x)=0.9^x and d. <span>j(x)=(4/5)^x</span>
Answer:
x = 40
Step-by-step explanation:
50 + 150 + 2x + x + x
200 + 4x
360 - 200 = 160
160 / 4 = 40
x = 40
50 + 80 + 40 + 150 + 40
2.5 mph is the answer I believe!
