Answer
x=-5
and
x=1
Explanation
The equation y = 2(x+2)^2 - 18 corresponds to a translation 2 units left and 18 units down, and a and a shrinkage about the x-axis with factor 2.
Making these transformations to y=x^2, we have:
Factoring:
The x-intercept are found when y=0, that is:
and
12/12, 4/4, and 2/2 there's three other ways you could do 6/6
<h2>
Value of x is 2 </h2>
Step-by-step explanation:
Surface area is given by 2x²+48x+88
We need to find x when surface area is 192.
A = 2x²+48x+88
2x²+48x+88 = 192
2x²+48x- 104 = 0
x²+ 24x - 52 = 0
( x - 2 ) ( x + 26 ) = 0
x = 2 or x = -26 not possible
Value of x is 2
I just did the math on my calculator and 300 divided by 60 is 5. So you are correct. Hope this helped!
