Answer:

2. $3x^2-13x-10$

Step-by-step explanation:

Expand (x−5)(3x+2) using the FOIL Method.

Step 2: Apply the distributive property.

$x(3x+2)-5(3x+2)$

Step 3: Apply the distributive property.

$x(3x)+x(2)-5(3x+2)$

Step 4: Apply the distributive property.

$x(3x)+x(2)-5(3x)-5(2)$

Simplify and combine like terms.

Step 5: Simplify each term.

$3x^2+2x-15x-10$

Step 6: Subtract 15x from 2x.

$3x^2-13x-10$

A cookie recipe calls for 1/3 of a cup of sugar and 1 1/2 cups of flour.

We need to find the unit rate of flour to sugar for the cookie recipe. It can be calculated as follows :

$U=\dfrac{\text{No of cups of flour}}{\text{No of cups of sugar}}\\\\=\dfrac{1\dfrac{1}{2}}{\dfrac{1}{3}}\\\\=\dfrac{\dfrac{3}{2}}{\dfrac{1}{3}}\\\\=\dfrac{3}{2}\times 3\\\\=4.5$
