94
(85+89+92+x)/4 = 90
(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)
266+x=360
(subtract 266 from each side)
x = 94
Answer: V = l w h
Step-by-step explanation:
Hi, to answer this question we have to apply the formula for the volume of a rectangular prism.
Volume of a rectangular prism (V) = Length x Width x Height
Replacing with the values given:
V = l w h
All values are multiplied (didn’t use x as a multiplication symbol to avoid confusion)

Answer:
x = -5/7
Step-by-step explanation:
8 1
---------- = ----------
x+3 x+1
Using cross products
8 (x+1) = 1 (x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x-x+3
7x+8 =3
Subtract 8 from each side
7x +8-8 =3-8
7x = -5
Divide each side by 7
7x/7 = -5/7
x = -5/7
