4c/15+5c/6 8c/30+25c/30 33c/30
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
if you mean 6-5c=-29:c=7
5c+7=23 -7 -7 5c=16 /5 /5 c= 3 & 1/5 or 16/5 thats really easy algebra 1 homework isn't it
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
4c/15+5c/6 8c/30+25c/30 33c/30
When c = -3 then 4c + 5c - 2 = [4 x -3] + [5 x -3] - 2 = -12 +(-15) - 2 = -12 -15 -2 = -29
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
The value of c is 6
9

The 'answer' is the number that 'c' must be, if 5c is really the same as -75.In order to find out what number that is, you could use 'algebra'.First, write the equation, so that you can look at it:5c = -75Now, use the law of algebra that says: "If equals are divided by equals,then the quotients are equal".The left and right sides of your equation are equals. Divide them both by 5,and that law says that the quotients on both sides will be equal:c = -15
5c-15 in bar model form = -10
2(5c + 2d)(5c + 2d)
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
C=7. I'll show my work. 5c-8=27. 5c=35. C=7
