Answer:
Step-by-step explanation:
To simplify 7/√x, we need to rationalize:
When we multiply the 2, we should get our answer:
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft

Answer:
B) -x+8y=56
Step-by-step explanation:
y=1/8x+7
Multiply by 8 to clear the fraction
8y = 8(1/8x+7)
Distribute
8y = 8*1/8x +8*7
8y = x+56
Subtract x from each side
-x+8y = x-x+56
-x+8y = 56
Answer:
8.03
Step-by-step explanation:
The answer can be any number of things, as long as the second number after the decimal point is a three. from left to right it goes tenths place, hundredths place, then thousandths place and so on.
I hope this helps!
