When I think of a number, double it, then add 7, I get 25. What number did I think of? ( Hint: Let the number be x)o

vivado [14]

Hey there!

The answer is $9$

We will start by forming an equation to solve this.

So we are starting with a number, $x$ , then doubling it and adding $7$ , which gives us 25.

So:

$2x+7=25$

Now we solve this equation:

$2x+7=25$

$2x=18$

$x=9$

Have a super awesome day!

24 , Factor: x²-9 A (x + 3XX-3) B (x+3)2 с (x-3) (x+3)(x+3)

Katarina [22]

Answer:

(x-3)(x+3)

Step-by-step explanation:

We are given the expression $\displaystyle \large{x^2-9}$ :—

To factor this expression, we have a formula for it which is difference of two squares:—

$\displaystyle \large{a^2-b^2=(a+b)(a-b)}$

You can also swap from $\displaystyle \large{(a+b)(a-b)}$ to $\displaystyle \large{(a-b)(a+b)}$ via multiplication property.

From the expression, factor using the formula above:—

$\displaystyle \large{x^2-9=(x^2)-(3)^2}\\\displaystyle \large{x^2-9=(x-3)(x+3)}$

Therefore, the factored expression is:—

$\displaystyle \large{\boxed{(x-3)(x+3)}}$
