I'm pretty sure the answer is A) 15 I could be wrong though
Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
Answer:
48in
Step-by-step explanation:
6 x 4 x 4
96
divide it by 2
48
E= 9 because you have to distribute -3.6 to E and -4
