Bearing in mind that a rectangle has a perimeter of length + length + width + width.
P = perimeter
L = length
x=width
P = 2L + 2x
P = 2(L+x) <==== perimeter of the base of the box.
check the picture below.
Answer:
6 and 3
Step-by-step explanation:
x^2 - 9x + 18 = 0
(x-6)•(x-3)=0
if x-6 = 0 then x = 6
and if x-3= 0 then x = 3
Answer:
y=45x+20
Step-by-step explanation:
y=45x+20
45 is constant, so every hour it takes, 45 dollars will be added (slope)
20 is the starting point (y- intercept)
Using formula y=mx+b
y=45x+20
