Determine whether the ratios are equivalent. 18 balloons for every 6 centerpieces
27 balloons for every 9 centerpieces

With both ratio= 3

The ratio are equivalent

Step-by-step explanation:

Ratio= number of balloons/ number of centerpieces

For

18 balloons for every 6 centerpieces

Ratio= 18/6

Ratio= 3

For

27 balloons for every 9 centerpieces

Ratio= 27/9

Ratio= 3

Value of each ratio= 3 and 3

3=3

So they are eqtand equivalent

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
