Answer:

B

Step-by-step explanation:

f(x) - g(x)

= 2x² - 4x - 3 - (x - 4)(x + 4) ← expand using FOIL

= 2x² - 4x - 3 - (x² - 16) ← distribute by - 1

= 2x² - 4x - 3 - x² + 16 ← collect like terms

= x² - 4x + 13 → B

How do you multiply anything not specific? sorry
Contact [7]
If it says 3×8 its like saying 8+8+8=21.
It's just a faster way of adding.

Anything multiplied by 0 is 0.

Anything multiplied by 10 just add a 0 to the end of the number example 10×2=20.

A taco stand sells tacos for $3.25 each. The stands expenses for the day are $210. Define your variables and write an inequality
Julli [10]
Given:

Let P= profit
let n= no. of tacos sold per day

Sol'n:

P= 3.25n-210
the profit needs to be positive, thus

3.25n>210

n>210/3.25

n> 64.615

they can only sell whole tacos, therefore they must sell at least 65 tacos to make a profit and that profit is:

P=3.25n-210

P=3.25*65 - 210

P= 211.25 -210

P= 1.25

$1.25 profit
