What is the volume of this rectangular prism?

Fynjy0 [20]

Answer: V≈5.21 cm³

Step-by-step explanation:

To find the volume of a rectangular prism, you multiply the length, width and height.

$V=wlh$

Since we were given the length, width and height, we can directly multiply them together.

$V=\frac{5}{2} *\frac{5}{3} *\frac{5}{4}$ [multiply]

$V=\frac{125}{24} =5.21 cm^3$

Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.

Determine if x + 2 is a factor of p(x) = x ^4 + 3x^ 3 + 4x ^2 - 8 and explain why.

zlopas [31]

X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /

is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
