For #1
you would do
8 + 8 + 5 + 5 = 26
so they use 26 inches of ribbon
for #2
since there is 8 sides and each side is 3 feet we multiply
8 x 3 = 24
so the perimeter of her collage room is 24 feet
for #3
its cut off...
15,000
3 multiplied by 5,000 is 15,000
The answer is A 27 because 7/9 = 21/27
Length = 6x - 12
Width = x
Area of a rectangle:
A = length x width
3744 = (x)(6x - 12)
3744 = 6x^2 - 12x
6x^2 - 12x - 3744 = 0
Use the quadratic equation to solve for x. The two solutions end up being 26 and -24. Since length is a scalar measurement, it can only be positive. Thus, the value of x is equal to 26 inches.
Width = 26 inches
Length = 6(26) - 12 = 144 inches
Hope this helps!! :)
