Answer:
L = 6, w = 2
Step-by-step explanation:
Let w = width of rectangle
Let L = length of rectangle
w = L - 4
Area of rectangle = Lw
L (L - 4) = 12
L^2 - 4L = 12
L^2 - 4L - 12 = 0
(L - 6)(L + 2) = 0
L - 6 = 0
L = 6 (the other option doesn't work because dimensions can't be negative)
w = L - 4
w = 6 - 4
w = 2
Double check
A = Lw
A = 6 x 2
A = 12
It matches so we are right.
Answer:
x = 1
Step-by-step explanation:
Given
5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )
5(2x - 8) = - 30 ( divide both sides by 5 )
2x - 8 = - 6 ( add 8 to both sides )
2x = 2 ( divide both sides by 2 )
x = 1
D and E are both binomials because they both have two terms
Median is the middle number
so in this picture median = 5
answer is 5
