Answer:

x = 7.2m

Step-by-step explanation:

Because it is a right triangle, you can use the Pythagorean theorem:

4^2+6^2 = x^2

16+36 = x^2

52 = x^2

sqrt52 = x

7.2 = x

GCF of 6x and x pls show work
vesna_86 [32]
GCF means the term(s) that 6x and x have.
The GCF is x because:
1. Using multiplication: 6x * x = 6x^2
becomes x(6+x) = 6x^2
GCF is x.

Good luck to you!
