Answer:

P(compact cars) = 4/25

Step-by-step explanation:

We know that there are 13 trucks, 8 vans, and 4 compact cars.

Let P denotes the probability of an event

Now we are asked to find the probability of compact cars

Number of favorable events = number of compact cars = 4

total number of outcomes = 13+8+4 = 25

hence, P(compact cars) = number of favorable events/total outcomes

                                       =4/25

Solve this in distributing -(5.3x-7y)-9.6
algol13

Answer:

-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y

Step-by-step explanation:

Given the expression

-\left(5.3x-7y\right)\times \left(-9.6\right)

=-\left(-9.6\right)\left(5.3x-7y\right)

Apply distributive law

a\left(b-c\right)=ab-ac

a=-\left(-9.6\right),\:b=5.3x,\:c=7y

so the expression becomes

=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y

=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y    ∵ -\left(-a\right)=a

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a

=9.6\times \:5.3x-7\times \:9.6y

=50.88x-7\times \:9.6y

=50.88x-67.2y

Therefore,

-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y

Can someone help me ASAP???!!
amm1812

Answer:

25x  ²−49y ²

Step-by-step explanation:

We need to find product of (5x+7)(5x−7y)

By using identity (a+b)(a−b)=a −b  ²

We have a=5x,b=7y

Thus (5x+7y)(5x−7y)=(5x)  ²−(7y)
