I will mark brainiest for the correct answer! Janelle wants to enlarge a square graph that she made so that each side of the new graph will be 1 inch more than twice the original side g. what trinomial represents the area of the enlarged graph?

Step-by-step explanation:

If the original square is x by x units, then the new one would be (2x + 1) by (2x + 1)  "one more than twice the original"

We can find the area of the new enlarged square by multiplying (2x+1)(2x+1) in whatever way you've learned it in class.  FOIL, box method, distribution...  You should end up with 4 terms, and then be able to combine two of them so you end up with a trinomial.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
