Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.

x= 630 x 100/2.25
x= 28000
Answer:
-6/5 = w
Step-by-step explanation:
-1/2w-3/3=1/3w
Add 1/2 w to each side
-1/2w+ 1/2 w -3/3=1/3w+ 1/2 w
-3/3 = 1/3w+ 1/2 w
-3/3 is 1
-1 = 1/3w+ 1/2 w
Get a common denominator for the right side of 6
-1 = 1/3*2/2 w + 1/2 *3/3 w
-1 = 2/6w + 3/6 w
-1 = 5/6 w
Multiply by 6/5 to isolate w
-1 *6/5 = 5/6*6/5 w
-6/5 = w
The answer is 305<span>°.
270</span>° + 35° = 305°.
