Answer:
length = 35ft, width = 20ft
Step-by-step explanation:
We are working with length (L), width (W), and area (A). We are asked to find the 2 dimensions. The question tells us that L = W + 15, so we can express L in terms of W. However, we still don't know what A is. Since we have 2 unknowns, we somehow need to develop 2 equations to get a solvable system.
We can set up the first equation using the relationship between L and W:

We can set up the second equation using the information in the second sentence:

Now we can plug the first equation, already isolated for A, into the second equation and solve for W:

A pretty nasty-looking equation actually becomes pretty easy to solve. We know the length is 15ft greater than the width, so if W=20, L=35.
Answer:
p= -12/5
Step-by-step explanation:
you have to subtract 2 from both sides
5p+2(-2)=-10 (-2)
5p= -12
5p/5= -12/5
p= -12/5
Answer:
A ≈ 615.75 cm squared
or 616cm squared when rounded off
We need the following to be true
a+2b = -a
a+4 = 2a - 3b
Let's look at the first equation.
a + 2b = -a
Subtract both sides by a
2b = -2a
b = -a
Substitute b= -a into the second equation
a+4 = 2a + 3a
a + 4 = 5a
4a = 4
a = 1
Just take the negative of that and you get the value of b.
b = -1
Your solution is a=1 and b = -1.
Have an awesome day! :)
