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:
Answer:
no
Step-by-step explanation:
no because some numbers could be negative and most number lines also contain 0. whole numbers are positive, non decimal/fractional, real numbers
Answer:
the x axis is 10, its interpretation is actually G, so on a graph instead of X and Y you would have G and T
600
explanation: well, since 140.3 divided by 600 is equal to 0.233833333... means that is that 140.3 is the 23 percent of 600
the product of x and 5.2 is 140. find the value of X
