Answer:
Step-by-step explanation:
Perimeter of a garden = 2(L+W)
Area of the gerden = LW
L is the length
W is the width
Given
Perimeter = 155ft
Area = 1400ft²
Substitute
1400 = LW
155 = 2L+2W
from 1;
W = 1400/L
Substitute into 2;
155 = 2L + 2(1400/L)
155 = 2L + 2800/L
155L = 2L² + 2800
2L²-155L + 2800 = 0
Factorize
L = 155±√155²-4(2)(2800)/4
L = 155±√24025-22400/4
L = 155±√1625/4
L = L = 155±40.31/4
L = 194.31/4
L = 48.82 feet and;
L = 155-40.31/4
L = 28.67ft
Hence the approximate length of the garden is at least 28.67 feet and at most 48.82 feet.
- 7/20 + -2/5 ? 16 / 20, I'm pretty sure

a quadratic function is letter A
Answer:
x^15
Step-by-step explanation:
x^3 * x^2 (x^3)^2 x^6
-------------------------------
x^2
First I will use the power of powers x^a^b = x^(a*b)
x^3 * x^2 x^(3*2) x^6
-------------------------------
x^2
x^3 * x^2 x^(6) x^6
-------------------------------
x^2
Next we will use the multiplication rule x^a * x^b = x^(a+b)
x^(3 +2+6+6)
-------------------------------
x^2
x^(17)
-------------------------------
x^2
Next we will use quotient rule x^a / x^b = x^(a-b)
x^(17 -2)
x^15
