Answer:
Step-by-step explanation:
x^2 + x^2 = 128 Normally you don't do this but rewrite the question
1x^2 + 1x^2 = 128
You actually do use 1 + 1 = 2 First time I've ever done that.
2x^2 = 128 Divide by 2
2x^2/2 = 128 / 2
x^2 = 64 Take the square root of both sides
sqrt(x^2)= sqrt(64)
x = 8
Answer:
8 =6 since 8 squared is 64 and 64 +64 or 64 times 2 is 128 that’s is your answer.
