Answer:

w < 2

Step-by-step explanation:

Subtract 8 from both sides.

-2w > -4

w < 2

Which expressions are equivalent to (2^2-9) (x + 3)?

mestny [16]

Answer:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

Step-by-step explanation:

Given

$(x^2-9)(x+3)$

Required

Select 3 equivalent expressions

$(x^2-9)(x+3)$

Express 9 as 3^2

$(x^2-3^2)(x+3)$ --- This is one equivalent expression

Take $x^2 - 3^2$ as difference of two squares

$(x-3)(x+3)(x+3)$ -- This is another equivalent expression:

Solving further:

$(x-3)(x+3)(x+3)$ becomes

$(x-3)(x+3)^2$ -- This is another equivalent expression:

Hence, the equivalent expressions are:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

Helppppppppppppppp pleaseeeeee!

stepan [7]

Answer and Explanation:

You got the first one right!

2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.

$3^{2*9} = 3^{18}$ , which is the answer

3. Here, you can split up the inside so that you have:

$2^5*(y^2)^5= 32*y^{2*5}=32y^{10}$ , which is the answer

Hope this helps! Please give me brainliest if possible.
