Answer: 4.500
Step-by-step explanation:
4x - 18 = 2 • (2x - 9)
2 = 0
2x-9 = 0
2x = 9
x = 9/2 = 4.500
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:
4*(5x^3-4)^3 * 3*5x^2 =
60x^2 (5x^3-4)^3
The answers are as follows:
Box 1) D
Box 2) .02D
Box 3) D + .02D
9 x 8 = 72
9 + 9 +9 + 9 + 9 +9 + 9 + 9 = 72
The dashed boundary line means that the solutions are not on the boundary line. It is used for < and >
