Haracio has 32 stamps. Jenna has 27 stamps. Gary has 16. You can solve this using matrices.
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:
I'm sorry I don't have answer but.
it's not C!
Angle F is equal to angle G so 5x + 18 = 7x-12 so you would solve for x which would equal 15
