Answer:

18q^2 - 52q + 32

Step-by-step explanation:

We can use the Distributive Property to solve this.

(2q-4)(9q-8)

2q(9q) + 2q(-8) + -4(9q) + -4(-8)

18q^2 - 16q - 36q + 32

18q^2 - 52q + 32

18q^2 - 52q + 32

The answer is 
B: x+y=700
2x+4.5y=1200


x - the number of student tickets sold,
y - the number of adult tickets sold

The total number of sold tickets is 700:
x + y = 700

Adult tickets sold for $4.50 each and student tickets cost $2.oo each. If they took in a total of $1,200:
2x + 4.50y = 1200

The system of equations is:
x + y = 700
2x + 4.50y = 1200

Answer:

the answer is 36ft by 48ft

Step-by-step explanation:

We first need to find the measurements of the green squares. Given the drawing is to scale we can say that each green square has equivalent measurements. Since there are 144 feet on each side of the original drawing, and 12 green squares on each side as well, then we need to divide 144 by 12 to find the measurements of one square. 144/12=12. the green squares are each 12ft by 12ft. to find the measurement of the jungle gym, we see how many green squares are on each side (there are 3 and 4) then multiply that number by 12. 4*12 I 48, and 3*12 is 36. Hence the measurements of 36ft by 48ft.
