Answer:
6 more lengths of gutter
Step-by-step explanation:
First, find the perimeter of the shed.
Use the perimeter formula, P = 2l + 2w
Plug in the length and width, then solve:
P = 2l + 2w
P = 2(8) + 2(8)
P = 16 + 16
P = 32
So, the perimeter is 32 feet.
Find how much more he needs by subtracting 20 from this, since he already has 20 feet of gutter.
32 - 20
= 12
So, he needs 12 more feet.
The store sells gutters in lengths of 2 feet, so divide this by 2:
12/2
= 6
So, he will need 6 more lengths of gutter
Answer:
–2x2 + 13
Step-by-step explanation:
( f o g)(x) = f (g(x))
= f (–x2 + 5)
= 2( ) + 3 ... setting up to insert the input formula
= 2(–x2 + 5) + 3
= –2x2 + 10 + 3
To find the total, all you need to do is add
. It gives you that, once you do that you get
Answer:
y=-10x + 25
Step-by-step explanation:
you can't collect like terms in this state so you just multiply all
Answer:
parallel : y = -3x + 3
perpendicular : y = 1/3x + 3
Step-by-step explanation:
rewrite 3x + y - 3 = 0
y = -3x + 3
parallel has the same slope
so
parallel : y = -3x + 3
perpendicular is negative reciprocal of the slope
so
-3x becomes 1/3x
so
perpendicular : y = 1/3x + 3
