Answer:
-3 X 7= -21
Step-by-step explanation:
Divide both sides by 2
x^2 = 128/2
Simplify 128/2 to 64
x^2 = 64
Take the square root of both sides;
x = √64
Since 8 * 8 = 64, the square root of 64 is 8
<em>x = -8 and 8</em>
<u>Answer: B -8 and 8</u>
Answer:
A and B
Step-by-step explanation:
3:4 multiplied by 2 is 6:8
