Factor 20x2 + 50x + 20.

1 answer:

5 0

$20x^2 + 50x + 20$

$GCF=10
$

$10(\dfrac{20x^2}{10} + \dfrac{50x}{10} + \dfrac{20}{10}$

$10(2x^2+5x+2)$

$10(2x^2+4x+x+2)$

$10(2x(x+2)+(x+2))$

$10(x+2)(2x+1)$

H^-16/h^x=1/h^24 can someone help me please

Basile [38]

Given:

Consider the equation is

$\dfrac{h^{16}}{h^x}=\dfrac{1}{h^{24}}$

To find:

The value of x.

Solution:

We have,

$\dfrac{h^{-16}}{h^x}=\dfrac{1}{h^{24}}$

Using properties of exponents, we get

$h^{-16-x}=h^{-24}$ $[\because \dfrac{a^m}{a^n}=a^{m-n},a^{-n}=\dfrac{1}{a^n}]$

On comparing both sides, we get

$-16-x=-24$

Add 16 on both sides.

$-x=-24+16$

$-x=-8$

Multiply both sides by -1.

$x=8$

Therefore, the value of x is 8.

Enrique and Yolanda collected 500 pieces of candy on Halloween. they gave half of their candy to charity. Yolanda took 180 piece

Ivenika [448]

500 − 250 = 250 pieces left after donation

Yolanda got 180 pieces....then Enrique got 70 pieces

So he got 70 /250 = 7/25 = 28% of the remaining candy
