Answer:

Price of one pepperoni pizza is $15.69

Step-by-step explanation:

We have that,

The price of 3 larger pepperoni pizzas is $49.57.

Since, the overall price included $2.50 of delivery charges.

Thus, the actual price of the 3 pizzas = $49.57 - $2.50 = $47.07

Then, the price of 1 pepperoni pizza will be \frac{47.07}{3} = $15.69

Hence, the price of one pepperoni pizza is $15.69

There is a proportional relationship between your distance from a thunderstorm and the time from when you see the lightning and
eimsori [14]

Answer:

Yes.

Step-by-step explanation:

The relation would be 3 = k*9  as there is a direct proportional relationship.

So k = 3/9 = 1/3  and we can write the relation as d = 1/3 t   where d=distance and t = time.

So if we double the time t we have:-

d = 1/3 * 18

= 6 kilometers.

So the distance is doubled.

Perform the multiplication, (7x2+a2)(x2–3a2)
aksik [14]

Answer:

The given multiplied expression is

(7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4

Step-by-step explanation:

Given expression is (7x^2+a^2)(x^2-3a^2)

To find the multiplication of the given expression :

(7x^2+a^2)(x^2-3a^2)

By using the distributive property to solve the given expression as below

(7x^2+a^2)(x^2-3a^2)=(7x^2)(x^2)+(7x^2)(-3a^2)+(a^2)(x^2)+(a^2)(-3a^2)

=7x^2.x^2-21x^2a^2+a^2x^2-3a^2.a^2

=7x^{2+2}-21x^2a^2+a^2x^2-3a^{2+2}  ( by using the property a^m.a^n=a^{m+n} )

=7x^4-21x^2a^2+a^2x^2-3a^4

Adding the like terms in the above expression we get

=7x^4-20x^2a^2-3a^4

Therefore (7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4

Therefore the given multiplied expression is

(7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4
