Answer:
2x^2 + 100x +800
1350 ft^2
Step-by-step explanation:
The length of the pool and walkway is x+40
The width of the pool and walkway is x +20+x = 2x+20
Area is length times width
A = (x+40) *(2x+20)
We can FOIL to find the area
first x*2x = 2x^2
outer x*20 =20x
inner 2x*40 = 80x
last = 40*20 = 800
Add these together
2x^2 +20x+80x+800
2x^2+100x+800
b. x=5
2x^2 + 100x +800
2(5)^2 +100(5) +80
2*25 +500+800
50+1300
1350 ft^2
You can reduce the first one by combining the ab and the ba term
Answer:
3
Step-by-step explanation:
x:5 = 18:30
Convert to the least common denominator 6x:30 = 18
:30
Divide each side by 6 6x = 18
x = 3
Given,
Adult Price(x) =8 $
Child Price(y) =6 $
So, 8x+6y=1500$ and also given 210 tickets were sold
So, x+y=210
By solving those two equations we get
No.of adult tickets sold = 120 & no.of child tickets =90
