The answer is 60.50 DO THE MATH LAZY!!!!!!!
How to get answer by Mimiwhatsup:
6(12m+12b−2b)
=(6)(12m+12b+−2b)
=(6)(12m)+(6)(12b)+(6)(−2b)
=72m+72b−12b
=60b+72m
4.888...%
428 + 22 = 450
22/450 = 0.4888...
0.4888... x 100 = 4.888...
(dots mean the decimal goes on forever)
Step-by-step answer:
Given an enlargement from preimage (ABC) to image (A'B'C').
Need to find scale factor.
Solution:
Scale factor = linear size of image / linear size of preimage.
From the accompanying diagram, we see that
L(preimage) = AC = 4 units
L(image) = A'C' = 12 units
Therefore
Scale factor = L(image) / L(preimage) = 12 / 4 = 3
