-9/3 + 4
-3 + 4 = 1
The answer to the question
Answer:
You have to divide
Step-by-step explanation:
2l+2w=perimeter <= equation for perimeter
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>
<span>and, since </span>
<span>w+4=l <= length is 4 greater than width </span>
<span>then l=4+4 </span>
<span>l=8</span>
Answer:
The answer would be 15.
Step-by-step explanation:
2x + 7 = x +4
2x = . x +1
x =11
2(11) =7
22-7
15.
Let's check if the ODE is exact. To do that, we want to show that if

then

. We have


so the equation is indeed exact. We're looking for a solution of the form

. Computing the total differential yields the original ODE,


Integrate both sides of the first PDE with respect to

; then

where

is a function of

alone. Differentiate this with respect to

so that



So the solution to this ODE is

i.e.
