A store has 7 red shirts, 15 black shirts, 13

AleksAgata [21]

Answer:First you have to add all of the shirts together, which gives you: 40

Since 15 of those are black, then you need to put those 15 over the total number of 40, making it 15/40.

Then you must simplify by the highest number that will go into both, and since that number is 5, it will then go into 15 three times and it will go into 40 eight times.

That leaves you with the answer of: 3/8

Use foil (a + 3)(a - 2)

blsea [12.9K]

Answer:

$\left(a+3\right)\left(a-2\right)=a^2+a-6=$

Step-by-step explanation:

Given expression is $\left(a+3\right)\left(a-2\right)$ .

Now we need to multiply this using FOIL.

F = First $=\left(a\right)\left(a\right)= a^2$

O = Outside $=\left(a\right)\left(-2\right)= -2a$

I = Inside $=\left(3\right)\left(a\right)= 3a$

L = Last $=\left(3\right)\left(-2\right)= -6$

Hence we get :

$\left(a+3\right)\left(a-2\right)=a^2-2a+3a-6=a^2+a-6=$

Answer:

fraction
denominator
product
numerator

Step-by-step explanation:

When you multiply a fraction by a whole number, the denominator in the product is the same as the denominator of the fraction. The numerator in the product is the product of the whole number and the numerator of the fraction.

That's the rule. It is derived from the fact that multiplication indicates repeated addition.

$\dfrac{2}{7}\times3=\dfrac{2}{7}+\dfrac{2}{7}+\dfrac{2}{7}=\dfrac{2+2+2}{7}=\dfrac{2\times3}{7}\qquad\text{for example}$
