Answer: (-4,9)
Step-by-step explanation:
Take the points and plot them on graph paper, revealing the midpoint
640=5×2⁷ so ⁷√640=2×⁷√5. So the expression can be simplified to 2 ⁷√6−5 ⁷√5. Note that -6=-1×6, and the 7th root of -1 is -1. This makes (-2)×(-1)=2, the coefficient of ⁷√6.
Answer:
|x + 5|= 7
-7<(x+5)<7
-7<x+5<7
-7-5<x+5-5<7-5
-12 < x <2
