Answer:
f(a) = 7a+7b+17
Step-by-step explanation:
2a+3b+4b+5a+17 = (2a+5a) + (3b+4b) +17
= 7a+7b+17

Hi there!
We can find the perimeter of a rectangle by using the following formula:
perimeter = 2 × width + 2 × length
In the question, we are given the following data: the length of the rectangle is 12 in and the perimeter is 56. Let's substitute this into our formula!
56 = 2 × width + 2 × 12
Multiply first.
56 = 2 × width + 24
Now subtract 24 from both sides.
32 = 2 × width
And finally, to find the width of the rectangle, divide both sides of the equation by 2.
16 = width
(we can eventually switch sides in the equation).
width = 16

3.15+4.5+.6=8.25, which is in the standard form for decimals.
hello :)
so the intial temperature was:
-10
and if it dropped 24 then this is the equation you want to solve
-10-24
so the new temperature would be
-34 degrees
hope this helped!
