WILL GIVE BRAINLIEST, THANKS, AND 5 STARS!<br> PLEASE HELP ME!

Answer:

-4 and 4

Step-by-step explanation:

<u>Method 1</u>

Apply Difference of Two Squares Formula: $a^2-b^2=(a+b)(a-b)$

Given $x^2-16=0$

Rewrite 16 as 4²

Therefore, $a^2=x^2$ and $b^2=4^2$

$\implies a = \sqrt{x^2}=x$

$\implies b=\sqrt{4^2} =4$

$\implies x^2-16^2=(x+4)(x-4)$

$\implies (x+4)(x-4)=0$

$\implies (x+4)=0 \implies x=-4$

$\implies (x-4)=0 \implies x=4$

<u>Method 2</u>

Given equation:

$x^2-16=0$

Add 16 to both sides:

$\implies x^2-16+16=0 + 16$

$\implies x^2=16$

Square root both sides:

$\implies \sqrt{x^2}=\sqrt{16}$

$\implies x=\pm4$

Therefore, x = -4, x = 4

Dale a las fracciones un denominador común.

El mínimo común múltiplo de 2 y 8 es 8.

1/2 = 4/8

comparar los numeradores de las fracciones

4/8 < 5/8

5/8 > 7/14

A shirt for $40, jeans for $50 and a watch for $35 are purchased at the mall. If 7% sales tax is charged, what will the total co

Inga [223]

Answer:B: 133.75$

Step-by-step explanation:

35 + 40 + 50= 125$

The total sales tax is 7%

We can put this into decimal form 7/100= 0.07

Because we want to just add 7% of the value back on we can also add 1 to that number

1.07

125 x 1.07 = 133.75
