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
Answer:
22%
Step-by-step explanation:
Divide 2,650 by 100:
2,650/100=26.5
Then divide 3233 by the dividend:
122=122%
Now you can see that there is a 22% percent increase over 100%, theefore making our answer 22%.
Have a great day, and mark me brainliest if I am most helpful!
