1) The radius would be r = x + 4y
<span>.... and the area would be A = pi ( x + 4y )^2 </span>
<span>2) x is not defined. You have to state the relationship of x with l ,w, and, h </span>
<span>3) The square prism is a cube. I assume that the edge is x. Then the perimeter of any one face is : </span>
<span>... p = 4x</span>
It will take 8 hours to fill the swimming pool. There is already 9,000 gallons filled, that leaves you with 12,000. 12,000 divided by the rate per hour 1,500. That gives you 8.
X= 6
Y= 8.5
I used Tan to find X and Cos to find Y
60% of what number is 348?
The answer is 580.
B. Is the right answer
First you have to take the common elements then use an identity/formula to get the rest
x^3 - 3x^2 + x-3
x^2 (x-3) +1 (x-3)
(x^2 +1) (x-3)
(x-1)(x+1)(x-3) {using a^2-b^2 on x^2-1^2}
