The radius of the Outer circle (with r₂) is 6 and the radius of the inner circle (with r₁) is 2. When objects are similar, they have a proportional relationship. If we take the outer circle and squeeze by one third, we get a radius of 6 x 1/3 = 2. On the other hand, if we start with the inner circle and stretch it by 3, we get a radius of 2 x 3 = 6.
Thus, to make r₂ similar, we use a scale factor of 1/3. The third choice is best.
Answer:
-4x-32 Can i please get a brainliest because this correct.
Step-by-step explanation:
−4(x+7)−4
Distribute:
=(−4)(x)+(−4)(7)+−4
=−4x+−28+−4
Combine Like Terms:
=−4x+−28+−4
=(−4x)+(−28+−4)
=−4x+−32
Answer:
=−4x−32
The answer is 169.
169 is a perfect square since 13 times itself (or 13²) is equal to 169.
√279=16.703
√169=13
√154=12.41
√115=10.72
