X - 4 when you use the foil method or multiplication
55.79 = 0.99<em>d + </em>39.95
55.79 - 39.95 = 15.84
0.99d = 15.84
0.99d/0.99 = 15.84/0.99
d = 16
2) Equation = 12.6 million = 4(x) + 1 million
12.6 million - 1 million = 11.6 million
11.6 million/4 = x
x = 2900000
hope this helps
the answer is C, (8x + 3)^2 :)
Yes, the relationship is proportional. 3 * 3.2 = 9.6. And 5 * 3.2 = 16.
