Answer:

(x + 2)(x + 3)

Step-by-step explanation:

To factor perfect square trinomials, we have to follow a certain trick, the two factor numbers must equal b (in this case 5x) when added and equal c (in this case 6) when multiplied.

Simply enough, two numbers that do this is 2 and 3.

Therefore, our factor numbers are 2 and 3, making the last eqaution (x + 2)(x + 3)

A cylinder has a volume of 320 cu in. and a height of 5". Find the radius of the cylinder. 10 in. 8 in. √8 in.

Reptile [31]

The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that

[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in

the answer is
8 in

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Vanyuwa [196]

Answer:

No, Sorry.

Step-by-step explanation:

Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.

Example) 1/2 - 3/4

$\frac{1}{2} - \frac{3}{4}$

Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.

$\frac{4}{8} - \frac{6}{8}$

The subtract from there.

$\frac{ - 2}{8}$

and then Reduce (if needed.)

$\frac{ - 1}{4}$
