The expression is: 12r-20 when simplified
To answer a quadratic like this, st everything equal to zero. 5r^2+12r=-4r^2-4 9r^2+12r+4=0 Ask yourself what two numbers add to get 12 that multiply to get 9*4=36 1*36 no 2*18 no 3*12 no 4*9 no 6*6 yes (3r+2)(3r+2) The first and last multiply to get 6 and the outside and inside multiply to get 6. That's (3r+)^2
12
8 x 12 = 96
x - 8 = 12 x - 8 + 8 = 12 + 8 x = 20
12r-20
12r - 20
The expression is: 12r-20 when simplified
-6r-5 = 7-12r 12r-6r = 7+5 6r = 12 r = 2
12r + 4 = 112, 12r = 108, r = 9
- 6r - 5 = 7 - 12r add 12r to both sides 12r - 6r - 5 = 7 - 12r + 12r 6r - 5 = 7 add 5 to both sides 6r - 5 + 5 = 7 + 5 6r = 12 divide both side integers by 6 r = 2 ---------- check in original equation -6(2) - 5 = 7 - 12(2) - 12 - 5 = 7 - 24 - 17 = - 17 checks
if you have 12r and you minus 4r it doesn't equal 48. it would equal 8r to find out what r is i would have to see the whole problem
12 Regular
I'll do ya one better - 12 plus 8 equals what?
20
The product of r and 12 is the result of multiplying the value of r by 12. In mathematical terms, this can be represented as r * 12. The product is the answer you get when you perform this multiplication operation.
96 divided by 8 equals 12.
