Answer:
2W + 56 = 78 , W = 10
Step-by-step explanation:
perimeter of rectangle = 2*the Length + 2*the Width
the ratio of the number of kids is 4:7
that means for every 7 kids we have 4 adults
7 kids ---- 4 adults
the difference is 3
we dived the difference of the kids between the difference of the ratio
150/3 = 50
the number we obtained must be multiply by the ratio of each part
7(50) = 350 number of kids
4(50)=200 number of adults
there are 200 adults at the fun fair
Answer:
A: 5x^2 + 42x + 16
B: 12x + 20
C: 351 units
Step-by-step explanation:
A: (5x + 2) * (x + 8) is the same as x(5x + 2) + 8(5x + 2). You just need to solve and simplify that for the area:
x(5x + 2) + 8(5x + 2)
= 5x^2 + 2x + 40x + 16
= 5x^2 + 42x + 16
B: You need to do 2l + 2w, or 2(5x + 2) + 2(x + 8):
2(5x + 2) + 2(x + 8)
= 10x + 4 + 2x + 16
= 12x + 20
C: You can either replace the x in the equation with 5 or replace the x in the figure itself with 5. I will replace the one in the figure with 5 because it is a lot easier:
(5(5) + 2) * (5 + 8)
= 27 x 13
= 351 units
