Answer:
a=-2
Step-by-step explanation:
5 go to another side by negative sign
and the coefficients of a will added
-16=8a
8 go to the other side
a=-2
First we find the scale factor. It went from a 11 cm length to 16.5 cm length....so we have to find out what to multiply 11 by to get 16.5.
11x = 16.5
x = 16.5 / 11
x = 1.5
and since we multiplied 11 * 1.5 = 16.5, then we have a scale factor of 1.5...so we now multiply the height of 4 by 1.5.
So the new height is gonna be : 4 * 1.5 = 6 cm <==
