Answer:
I think its 1.2
Step-by-step explanation:
Long way:
2(x-3)(x+3) = 2(x*x + 3*x - 3*x - 3*3)
2(x-3)(x+3) = 2(x^2 - 9)
2(x-3)(x+3) = 2x^2 - 2*9
2(x-3)(x+3) = 2x^2 - 18
Shortcut way:
Using formula (x+a)(x-a) = x^2 - a^2, where a = 3, in the case of (x+3)(x-3), so we have
(x+3)(x-3) = x^2 - 9.
Then, we multiply that by 2, which gives 2x^2 - 18.

Hi There!

Baseball Bats:
43 x 0.45 = $19.35 as the amount off.
43 - 19.35 = $23.65 with the discount.
23.65 x 2 = $47.3 for two bats.
-----------------------------------------------------
Glove:
28 x 0.25 = $7 as the amount off.
28 - 7 = $21 with the discount.
-----------------------------------------------------
Together:
21 + 47.3 = $68.3 as the total before taxes.
-----------------------------------------------------
With Taxes:
68.3 x 0.055 = $3.7565 as the tax amount.
68.3 - 3.7565 = $64.5435
-----------------------------------------------------
Answer:
Not Rounded: $64.5435
Rounded: $64.54

Answer:
Domain: [-3, 3]
Range: [-1, 5]
Step-by-step explanation:
Reminder: domain is the x values that will make the function defined, and range is the possible y values the function could get.
Keeping that in mind, you can see that the domain of this function is [-3, 3] (using interval notation) and the range is [-1, 5].
Or, you could express the domain as -3≤x≤3 and the range as -1≤y≤5.
I hope this helped.
