Question

Determine if the given value makes the equation true or false. For x3 – 8 = 15, if x = 69

Answer 1

False

Explanation:

69 * 3 =207

207 - 8 = 199

x3 - 8 = 199 for x = 69

Answer 2

(69)(3)−8 = 15

199≠15

False

Explanation:

hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
