Answer:
width=20m
length=108m
Step-by-step explanation:
w=x
l=6x-12
p=2(w+l)
256=2(x+6x-12)
256=2(7x-12)
256=14x-24
256+24=14x
280=14x
x=280/14
x=20
recall,
l=6x-12=6*20-12=120-12=108
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (8, - 4) ← 2 points on the line
m = = =
The line crosses the y- axis at (0, - 6 ) ⇒ c = - 6
y = x - 6 → B
If both the length and width are doubled, then the entire thing is quadrupled, so it will go from 8 feet squared to 32 feet squared.
Answer:
(n+2)(n+1)
Step-by-step explanation:
Write out the numerator and cancel common factors:
(n+2)!/n! = (n+2)(n+1)n!/n! = (n+2)(n+1)
_____
You might be expected to multiply it out:
= n·n +2·n +n·1 +2·1
= n² +3n +2
