Answer:
64 ft^2
Step-by-step explanation:
(x+7)(x-2)=90
x^2-2x+7x-14=90
x^2+5x-104=0
factor
(x+13)(x-8)=0
x=-13
x=8 ft original square side
area=8x8=64
This one is A. they are complementary
1. 1/3 - 7/8
rewrite the complex fraction as a division expression
show the complex fraction in simplest form.
step 1
we have

Multiply the first term by 8/8
so
(1/3)*(8/8)=8/24
Multiply the second term by 3/3
(7/8)*(3/3)=21/24
step 2
substitute in the original expression
8/24 -21/24
the fractions have the same denominator
so
(8-21)/24
-13/24
therefore
the answer is
-13/24
Answer:
183.927844 kg²
Step-by-step explanation:
Calculation for the weight variance:
Given that s =13.5620 kg
The Variance will be the square of the Standard Deviation
S²=13.5620 kg²
S²=183.927844
The units of the variance will be the units of the Standard Deviation Squared which is Kg²
Therefore the variance of their weight will be:
183.927844 kg²
