It is (c+d)
you can basically use FOIL (first,outside,inside,last) to solve this.
you know the first term of the factor has to be C because of the c^2
the second then has to be D because you haven't seen D in the factor yet and it is in the equation.
then you know from the equation that the terms with D are not negative so D isn't negative so you have form the information above (c+d)
y=2x+6
y=2x+2
Solve y=2x+6 for y
Substitute 2x+6 for y in y=2x+2
y=2x+2
2x+6=2x+2
Add -2x to both sides
2x+6-2x= 2x+2-2x
6=2
Add -6 to both sides
6-6=2-6
0=-4

Answer:
0.5x + 2
Step-by-step explanation:
You switch x and y and then solve for x to find the inverse.
To answer this problem we have to use two different variables. For example...
L = Length
W = Width
So we know that the definition of perimeter is
L + L + W + W (or all the sides added up)
Now we also know that The Length is 4 times longer than the width.
So we can write 4W to replace the L
So in the given equation we set up Replace every L with 4W
4W + 4W + W + W = 60 meters
now group our W's
10W = 60 divide both sides by 10 to get W to be alone
÷10 = ÷10 It cancels on the left side and we solve on the right side.
W = 6
So now that we know what the width equals we can find what the length equals .
Remember this?
4W = L (plug in 6 for W)
4(6) = L
So L = 24
Our dimensions of this rectangle are length 24, width 6.
Good Luck! :)
