The S<span>urface area of the rectangular prism is 238
Formula A=2(wl+hl+hw)
insert the numbers 2(4*11+5*11+5*4)
11*4=44
5*11=55
5*4=20
add them all up
44+55+20=119
new equation 2(119) or 2*119
2*119=238
Hope this helps :D</span>
Function 1 has a maximum at y = 1
Now we need to find the maximum of Function 2 by completing the square:
-x^2 + 2x - 3
= -(x^2 - 2x) - 3
= -(x - 1)^2 +1 - 3
= -(x - 1)^2 - 2
Therefor the turning point is at (1, -2) and the maximum is at y = -2
-2 < 1, therefor Function 1 has the larger maximum
5(2y - 2) + 4 Distribute/multiply 5 into (2y - 2)
(5(2y) - 5(2)) + 4
10y - 10 + 4 Combine like terms (-10 + 4)
10y - 6
If you looked it up online you could find it. look on safari
When you factor the equation you get:
(n-2)(3n²+4)
