Answer:
Answer C: m = 26, f = 22
there is a typo in answer D.
Step-by-step explanation:
There are 48 vehicles, so m + f = 48.
They have 140 wheels, so 2m+4f = 140.
You can rewrite the first as m = 48-f and then plug it into the second:
2(48-f) + 4f = 140 =>
96 - 2f + 4f = 140 =>
2f = 140 - 96 =>
2f = 44
f = 22
m = 48 - 22 = 26
Answer:
The height is 5 and the base is 9
Step-by-step explanation:
The area of a parallelogram is given by
A = bh
45 =x(x+4)
Distribute
45 =x^2+4x
Subtract 45 from each side
45-45 =x^2 +4x-45
0 = x^2 +4x-45
Factor
What two numbers multiply to -45 and add to 4
9+-5 = -45
9-5 =4
0=(x+9) (x-5)
Using the zero product property
0= x+9 0 = x-5
x=-9 x=5
Since length cannot be negative
x=5 is the solution
x=5
x+4 = 5+4 =9
