(3) 15x-30
Distribution
(1) x to the 6 power
You add the powers when they are being multiplied
(2) 2x squared + 7x + 12

Answer:
Step-by-step explanation:
To find x, the following equation is generated given the available information:
Cross multiply
Collect like terms
15. MP(5,11) S(3,5) M(x,y)
(3+x)/2 = 5 x=7
(5+y)/2 =-11 y=-27
M(7,-27) is the other point
