Answer:
Perimeter of square: 4*side
Let's take the side to be 'x'
4x = 40
x = 10
Therefore, EACH SIDE = 10ft.
Answer
x = 2 + √15/11, 2 - √15/11
Decimal Form:
x = 0.53390757
x = -0.17027121

Answer:
width = 7 and length = 9
Step-by-step explanation:
Let's assume width = w, and length = 2 + w
So area of a rectangle = width * length
63 ft² = w (2 + w)
63 = 2w + w²
w² + 2w - 63 = 0
Use the quadratic formula to solve this
here, a = 1, b = 2 and c = -63
w = 7 or -9
The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.
Width = 7 and Length = 7+2 = 9
The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
Answer:
=35
Step-by-step explanation:
3(3) ^2 + 2(4)
= 3(9) + 8
= 35
Where you see a, substitute with 3 and where you see b, substitute with 4
Just follow the steps above.
