(36 - 3 x 4) \ (15 - 9 \ 3) = my answer is 66 is this correct

No. The correct answer is 2.

Step-by-step explanation:

First, open the parentheses

Now, multiply the numbers

36-3*4 / 15-9/3

==>36-12 / 15-9/3

Change the 9/3 to a three

Subtract the numbers

36-12 / 15-3

==> 24/15-3

==> 24/12

Reduce the fraction

==>2

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
