Let's use the variable x to represent the number of jeans and y to represent the number of t-shirts.

The price paid for x jeans is 20x and the price paid for y t-shirts is 10y.

If the total cost is $350, we can write this equation:

\begin{gathered} 20x+10y=350 \\ 2x+y=35 \end{gathered}

The number of items is 25, so we can write a second equation:

x+y=25

Subtracting the first and second equations, we have:

\begin{gathered} 2x+y-(x+y)=35-(25) \\ 2x+y-x-y=10 \\ x=10 \end{gathered}

Now, solving the second equation for y:

\begin{gathered} x+y=25 \\ 10+y=25 \\ y=25-10 \\ y=15 \end{gathered}

Therefore she bought 10 pairs of jeans and 15 t-shirts.

Factorise the following:<br><img src="https://tex.z-dn.net/?f=%7B3x%7D%5E%7B2%7D%20%20%2B%205x%20-%2012" id="TexFormula1" title=

Answer:

(x + 3)(3x - 4)

Step-by-step explanation:

Given

3x² + 5x - 12

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 12 = - 36 and sum = + 5

The factors are + 9 and - 4

Use these factors to split the x- term

3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )

= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term

= (x + 3)(3x - 4)

Thus

3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form
