y = plus-or-minus StartRoot StartFraction x + 10 Over 7 EndFraction EndRoot
Step-by-step explanation:
Just took the test.
B is the answer hope this helps
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />
