Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
X = 2 for the first one by cross multiplying......sorry about not having time for the other 2
2-10 = -8 I'm not sure what the 5,6,7,8,9,10 means if you tell me i might be able to help you
26 feet * 12 inces per foot / 7.5 inches = 41.6, which is 41 full bracelets
