I thought you made it zero...
Like for this one, adding 10 on both sides.
-13 would become -3 and then you would use the Quadratic formula.
Though I may be wrong
You did not provide us with equations to select.
Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)
Did you follow?
Answer:
The length of a side of the base is ![5\ in](https://tex.z-dn.net/?f=5%5C%20in)
Step-by-step explanation:
we know that
The volume of a rectangular prism is equal to
![V=Bh](https://tex.z-dn.net/?f=V%3DBh)
where
B is the area of the base of the prism
h is the height of the prism
we have
![V=175\ in^{3}](https://tex.z-dn.net/?f=V%3D175%5C%20in%5E%7B3%7D)
![h=7\ in](https://tex.z-dn.net/?f=h%3D7%5C%20in)
Substitute the values and solve for B
![175=B(7)](https://tex.z-dn.net/?f=175%3DB%287%29)
![B=175/(7)](https://tex.z-dn.net/?f=B%3D175%2F%287%29)
![B=25\ in^{2}](https://tex.z-dn.net/?f=B%3D25%5C%20in%5E%7B2%7D)
Remember that the base is a square
so
![25=b^{2}](https://tex.z-dn.net/?f=25%3Db%5E%7B2%7D)
![b=5\ in](https://tex.z-dn.net/?f=b%3D5%5C%20in)
