Answer:

X=-2or,-3

Step-by-step explanation:

X^2+5x+6=0

or,x^2+2x+3x+6=0

or,x(x+2)+3(x+2)=0

or,(x+3) (x+2)=0

Either,

x+3=0 x+2=0

or,x=-3 or,x=-2

Answers please! I’m finding the volume and i don’t really get it

MrRa [10]

Answer:

V = 13/2

Step-by-step explanation:

When finding volume you must know the formula on doing so.

<em>Volume = length × width × height</em>

length = $2\frac{1}{2}$ --> $\frac{5}{2}$

width = $2\frac{1}{2}$ --> $\frac{5}{2}$

height = $3\frac{1}{4}$ --> $\frac{13}{4}$

<u>mixed number --> fraction</u>

$V = \frac{5}{2} x \frac{5}{2} x \frac{13}{4}$

$V = \frac{25}{4} x \frac{13}{4}$

$V = \frac{325}{8}$ or $\frac{13}{2}$
