The garden area is given by:
Substituting values we have:
Rewriting we have:
The perimeter is given by the sum of the sides.
We have then:
Where,
CB is given by:
Substituting values:
Answer:
The area of the garden is 72 square feet. The length of fencing required to completely enclose the garden is 36 feet.
Answer:
.021
Step-by-step explanation:
7 + 8 + 4 + 10 = 29
(8/29)³ = .021
The answer is 11, because 6x6 = 36 and 5x5 = 25, meaning 36-25= 11.
The answer is c 10. You can see if you plug it in
Answer:
x ≈ - 4.12 , x ≈ 0.12
Step-by-step explanation:
Given
2x² + 8x - 1 = 0 ( add 1 to both sides )
2x² + 8x = 1 ← factor out 2 on the left side
2(x² + 4x) = 1
To complete the square
add/ subtract (half the coefficient of the x- term )² to x² + 4x
2(x² + 2(2)x + 4 - 4) = 1, that is
2(x + 2)² - 8 = 1 ( add 8 to both sides )
2(x + 2)² = 9 ( divide both sides by 2 )
(x + 2)² = ( take the square root of both sides )
x + 2 = ± = ± = ± ( subtract 2 from both sides )
x = - 2 ± 1.5 , thus
x = - 2 - 1.5 ≈ - 4.12 ( to 2 dec. places )
x = - 2 + 1.5 ≈ 0.12 ( to 2 dec. places )
