Answer: 7
Step-by-step explanation:
denotes the intersection of A and C, or in other words, how many elements are shared between them.
The number of elements is 2 + 5 = 7
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
Step-by-step explanation:
The distance around a figure is called the perimeter.
Hope this helps :)
Step-by-step explanation:
well first you need to divide all the percents by 100.
40% = .40
30%= .30
and now you need to multiply those two by 950.
.40/950=4.20
.30/950=3.15
