Please help me with this question (5y + 2)2 − 96 = 0

Answers

simplify the equation with pemdas
first parentheses

distributive property
a(b+c)=(ab)+(ac)

(5y+2)2=(10y)+(4)
10y+4-96=0
10y-92=0
add 92 to both sides
10y=92
divide both sides by 10
y=9.2

How many square feet of paper do you need to cover a cube with a side 10 in. long? Round your answer to two decimal places.A. 4.17 sq ft
B. 86.40 sq ft
C. 6.94 sq ft
D. 82.52 sq ft

Answers

Answer: A. 4.17 sq ft

Step-by-step explanation:

The total surface area of cube is given by :_

T.A.=6(side)^2

Given: The side of cube = 10 in.

We know that 1 feet = 12 inch

∴1\ in.=(1)/(12)\ ft

Therefore, the  side of cube =10*(1)/(12)\ ft=(10)/(12)\ ft

Then the  total surface area of cube is given by :_

T.A.=6((10)/(12))^2\n\n=6((100)/(144))\n\n=4.16666666667\approx4.17\ sq\ ft
10 in = 0.83 ft= (5)/(6) ft\n A=6* ((5)/(6)) ^(2)=4.17

So the answer is A. 4.17 sq ft.
