Since the 3 is outside of the parentheses you would have to distribute it. This means that you multiply x by 3, then you multiply 4 by three to get 3(x) + 3(4). SO 3 time x equals 3x plus 3 time 4 equals 12
This would give you 3x+12

To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and -4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y(y-2)

2y^2 - 4y in completely factored form is 2y(y-2)

First you have to distribute the negative(=-1) with the numbers in the parentheses.
-1×9=-:
-1×-3x=3x
You now have:
4x-9+3x=8x-1
Now combine like terms:
4x+3x=7x
Now you have:
7x-9=8x-1
Now isolate that x:
7x-8x=-x
-1+9=8
You now have:
-x=8
Divide by -1 and get:
x=-8

If her hourly wage is $52 which equation represents the proportional relationship between the wages she earns (w) and the number of hours (h)? w=52h w=26h 1/26w=h 1/52w=h Answer The equation represented the proportional relationship between the wages she earns (w) and the number of hours (h) . w=52h Reason As given Maya is interning at a law firm over the summer and is paid by the hour. If her hourly wage is$52

w = wages maya earns

h = number of hours

Than the equation becomes in the form

w = 52× h

w = 52h

Therefore the wages maya earns is represented by w = 52h .
