A number squared would be x squared (x^2)
The product of x squared and ten is 10x^2
Then subtract nine
10x^2 - 9
Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion, that is
= ( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9
I’m not rlly good at math but the answer should be 25.13
