The product of two numbers is 21. if the first number is -3, which equation represents this situation and what is the second number?
a.
the equation that represents this situation is x - 3 = 21. the second number is 24.
b.
the equation that represents this situation is 3x = 21. the second number is 7
c.
the equation that represents this situation is -3x = 21. the second number is -7.
d.
the equation that represents this situation is -3 + x = 21. the second number is 18.

C.

The equation that represents this situation is -3x = 21. The second number is -7.

Step-by-step explanation:

 The equation that represents this situation is -3x = 21. The second number is -7 (option C).

Step-by-step explanation:

Hi, the correct option is C.

We have to analyze the information given to write the equation and corroborate the option chosen.

So:

first number = -3  

Product means the result of multiplication, in this case, the product is number 21.

Mathematically speaking:

-3x= 21

x = 21/-3

x = -7

In conlclusion, he equation that represents this situation is -3x = 21. The second number is -7 (option C).

d. is the correct answer

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
