Hi there!
Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3

Answer:
90
Step-by-step explanation:
"how many one inch squares" is basically saying surface area. just find the area of each side and add them.
80x 40 x 20 feet is your answer! Hope this helps
Answer:
-10/3, 10/3
Step-by-step explanation:
<em>(In this answer I will use y' to denote the derivative of y with respect to t. You shouldn't normally do this because y' normally means the derivative of y with respect to x but I'll be a bit messy for this case)</em>
First calculate the derivatives:
.
Then plug the derivtes y'' and y into the equation:
Solve the equation for k:
So then we have that satisfies the differential equation when or when (or both). The solutions to these equations are:
I understand that looks a bit complicated and I doubt you would have to give your answers in terms of t so if it asks for a separated list of answers I would go for:
k = -10/3, 10/3.
