m2 + 12m + 20 = ( m + 2)(m + 10)
r - 20
what is $125.00 plus 20%
250 * 0.08 = 250 * 2 / 25 = 500/25 = 20 250 + 20 = 270
245 r = 100 % 24.5 r = 10 % 49 r = 20 %
2+2+2+10+5+5+5+20+20+20+20+20+20=151
-9r = 20 + rsubtract r from both sides-10r = 20divide both sides by -10r = -2
r=-29
(r + 2)(r + 2)
10 plus 20-2 - 11 plus 3 is equal to 20.
That depends on what the question is. What you gave is simply a relationship between two variables. You can simplify it like this: 4x + 8 = 2r + 20 (4x + 8) / 2 = (2r + 20) / 2 2x + 4 = r + 10 2x + 4 - 4 = r + 10 - 4 2x = r + 6 You can then solve for x by dividing both sides by two: 2x / 2 = (r + 6) / 2 x = r/2 + 3 You could also solve for r by subtracting six from both sides, and rearranging the equation: 2x = r + 6 2x - 6 = r + 6 - 6 2x - 6 = r r = 2x - 6 r = 2(x - 3)
r is worth - 0.542 mathematically if 1 2 r plus 6.5.
r2 + r - 20 = 0(r + 5)(r - 4) = 0r + 5 = 0 or r - 4 = 0r = -5 or r = 4
2 + 20 = 22
2 + 4 + 6 + 20 = 32
it is 20 and 20 divided by 4 = 5
I come up with 20.
