7x+2y=48
7x+2(3)=48
7x+6=48
Subtract 6 on both sides.
7x=42
divide 7 on both sides
x=6
Answer:
It is 83.35 Unless your rounding up then it is 84 dollars
Step-by-step explanation:
The given expression is

THe given expression is a rational expression, and rational expression should not have 0 in the denominator.
Moreover, the denominator is a square root term, and square root don't have a value for negative number .
Therefore 2x+10 must be greater then 0. That is

Therefore the required domain in set builder form is
{
}
The surface area of a cylinder is:
A=2pr^2+2prh
A=2pr(r+h) we are approximating π as 3.14, r=12, and h=8 so
A=2(3.14)12(12+8)
A≈1507.2
A≈1507 m^2 to nearest m^2
