•i need with this & a explanation!

The answer is C=10

This is the Pythagorean theorem, it solves for the hypontunuse. Basically it tells you the missing sides length.

It’s really simple once you get the hang of it. The formula is

A^2+b^2=c^2

Plug in the side lengths you have (6 and 8)

6^2+8^2=c^2

36+64=c^2

100=c^2

DO NOT PUT 100 AS ANSWER

You then take the square root of 100, to get 10^2

3x + 4y -25 =0 represents the amount of change sianna should recieve

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
