Step-by-step explanation:
Answer:
8:7
Step-by-step explanation:
A <em>scale</em> factor (SF) is the ratio of two corresponding side lengths in similar figures.
The two circles are the similar figures, and the SF is the ratio of their corresponding radii.
SF = outer radius/inner radius
= (35 + 5)/35
= 40/35
= 8/7
The scale factor is 8:7.
<span> (-2.9a + 6.8 ) + (4.4a - 7.37)
=</span> -2.9a + 6.8 + 4.4a - 7.37
= - 2.9a + 4.4a + 6.8 - 7.37
= 1.5a -0.57
Answer: 1.5a - 0.57
