Help i dont understand how to do this the question is "Put your answer in decimal form."

x = 2.5

Step-by-step explanation:

Hypotenuse ² = opposite ² + adjacent ²

(x + 4)² = x² + 6²

x² + 8x + 16 = x ² + 6²

x² + 8x + 16 - x² = 6²

8x + 16 = 36

8x = 36 - 16

8x = 20

x = 20/8

x = 2.5

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
