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:—

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

What number is equal to 4^3

eimsori [14]

1.) 4^3= 64

2.) a^2 + b^2=c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169= c^2
$c = \sqrt{169} = 13$
3.) a^2 + b^2 = c^2
24^2 + b^2 = 26^2
576 + b^2 = 676
b^2 = 100
$b = \sqrt{100} = 10$

What is the result of isolating y^2 in the equation below (x+6)^2+y^2=1

katrin [286]

Answer:

(x+6)^2 + y^2 = 1 then isolate y^2 by subtracting (x +6)^2 from both sides, we get

y^2 = 1 - (x + 6)^2

expanding the right side, we now have

y^2 = 1-(x^2 + 12x +36)

y^2 = 1-x^2-12x -36

y^2 = -x^2 -12x - 35 therefore the solution is choice A
