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
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.

Shaded area = rectangle - triangle
(5 × 9) - (½ × 3 × 4)
45 - 6
Answer: the answer is the second one.
Hope this helps
3x - 2 = 4(2x-8)
3x- 2 = 8x- 32
3x-8x = -32+2
-5x = -30
x = -30/-5
x = 6
I think its the lifo method im not sure but i had a question like this in class
