1. Find the value of x. in the below given diagram

To find the hypotenuse, we use pythagorean theorem, a^2 + b^2 = c^2

3 squared + 5 squared = x squared

x squared = 34

to get x on its own, we need to square root 34, therefore your answer is the square root of 34 inches or 5.83 inches (2dp)

Hope this helps!!

Ais the correct answer

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
