Add/subtract the "d" variables:

Answer:
2
Step-by-step explanation:
subtract 8 from 14 and that gives you six which you have to multiply 3 and 2 to get six so y equals 2
A. 12 mm
The Pythagorean Theorem states that a^2 + b^2 = c^2 with a and b being lengths of legs and c being the length of a hypotenuse. So we can use our givens to solve for the remaining leg.
9^2 + b^2 = 15^2
81 + b^2 = 225
b^2 = 144
b = 12
Scale factor= length of the copied figure /length of the original
You count the units from the graph
Figure A(the original) is 6
Figure B ( the copied figure) is 2
=2/6
