Answer:
r = 1
Step-by-step explanation:
In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.
Distributive Property:
a(b+c) = ab + ac
Now, lets solve this:

As we have seen the value of r is "1"
It is prime because nothing equals it other than 5x1
B (2+x) +3y
Other examples include <span>(14 + 6) + 7 = 14 + (6 + 7)
because </span><span>Adding 14 + 6 easily gives the sum of 20 to which we can add 7. The right hand side of the equation is where we add 14 and 13. Both sides will result in 27.</span>
Y=4x-21 I’m pretty sure is the answrr.
8 - (-4) [2 negatives become a positive]
8 + 4 = 12
A.) - 8 + 4 = -4
B.) -8 + (-4) = -12
C.) 8 + (-4) = 4
D.) 4 - (-8) = 4 + 8 = 12
Your answer is D
