The area is found by multiplying the length by the width.
The original area = 60 x 40 = 2,400 square feet
He wants to make it 1/2 that size, so the new size would be 2,400 / 2 = 1,200 square feet.
To find the length divide the new area by the new width:
1,200 / 30 = 40
The new length should be 40 feet.
Answer:
d 7(13)
Step-by-step explanation:
Subtract $7.89- 0.49 and thats your answer
x^2+9x+20 = (x+5)(x+4) / 2x+8 = 2(x+4)
The (x+4)'s cancel each other out, so the simplified answer your left with is
x+5/2
