Divide the sides of the larger triangle by the corresponding side of the smaller one:
18/7.2 = 2.5
Figure A is 2.5 times the size of figure B
The scale factor is 2.5
Answer:
The solution is B. The graph in choice B is a line and therefore fits the definition of a linear function. sorry if this did not help
Plug in 4 for r and 1 for s
r+s^2
4+1^2
Evaluate exponents first (order of operations)
4+1
Add
5
Final answer: 5
