If you would like to expand and simplify 3 * (x + 2) + 2 * (x - 1), you can do this using the following steps:

3 * (x + 2) + 2 * (x - 1) = 3 * x + 3 * 2 + 2 * x - 2 * 1 = 5 * x + 6 - 2 = 5 * x + 4

The correct result would be 5 * x + 4.

1.Find the zeros of f(x) = x2 - 9

Marat540 [252]

So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket

the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well

A boy bought an article for £9. He spent £4

Marina86 [1]

Answer:

Profit % = 39%

Step-by-step explanation:

Cost price of the article = 9

Price for repairing = 4

Therefore, Total cost of the article = 9 + 4 = 13

Selling price of the article = 18

Profit = 18 - 13 = 5

Hence,

$Profit \% = \frac{Profit}{Cost \ price} \times 100\\\\$

$= \frac{5}{13} \times 100\\\\=38.46 \%\\\\=38.5 \%$

Profit percent (to the nearest %) = 39%
