Answer:
x = 10
Step-by-step explanation:

→ In an equation our aim is to isolate 'x' and find the value and so the first step is to square both sides to get rid of the square root
x² - 36 = 64
→ Add 36 to both sides to isolate x²
x² = 100
→ Square root both sides to isolate x
x = 10
L=22w (w=width, l=length)
l*w=2626
Substitute 22w for l, getting 22w^2=2626. Divide by 22 to get 119.36 (and more decimals!), and square root that to get 10.9 (rounded) for the width and 240.4 (rounded) for the length

Answer:
-9/10 =r
Step-by-step explanation:
7/10=r-(-8/5)
Subtracting a negative is like adding
7/10=r+(8/5)
Subtract 8/5 from each side
7/10 - 8/5=r+(8/5) - 8/5
7/10 - 8/5 = r
Get a common denominator
7/10 - 16/10 = r
-9/10 =r
