Deandre is using the expression 3b + 4 to represent the number of cars in the mall parking lot. there are three times as many cars as parking spots, and there are four cars parked illegally. what does b represent?

b represent Number of parking slots.

Step-by-step explanation:

We are given Expression representing number of cars in the parking lot = 3b + 4

Given statement is three times as many cars as parking spots. Four cars also parked illegally.

In the given expression 3b represent three times as many cars as parking spots. And 4 represent Four cars also parked illegally.

So, In 3b b representing Number of parking slots.

Therefore, b represent Number of parking slots.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
