Answer:
Lets call the dimensions of the rectangle l and w. The new dimentions are 6l and 6w. The area of the first rectangle is lw. The area of the second rectangles is 36lw. 36lw/wl is the answer, and this is 36.

Answer:
C is correct.
Step-by-step explanation:
The angles in the triangle have to add up to 180 and 36+36+108 is 180.
The solutions are C = 2 and C = -2
We can find this by solving for C.
C^2 - 4 = 0 ----> add 4 to both sides
C^2 = 4 ----> Take the square root of both sides
C = 2
However, since we used the square root function, we have to include a negative form of the answer as well as the positive one we found.
Answer:
2a = 108
Step-by-step explanation:
the 3 angles of the triangle add to 180
lets call the unknown angle in the triangle y
a+10 + y + 44 = 180
we also know that 2a+ y = 180 because it makes a straight line
solve this for y by subtracting 2a from each side
2a +y = 180
y = 180 -2a
now we can substitute this into the triangle equation
a+10 + y + 44 = 180
a+10 + 180 -2a + 44 = 180
combine like terms
-a +234 = 180
subtract 234 from each side
-a = --54
divide each side by -1
a =54
the exterior angle is 2a
2* 54
108
