Answer:
Step-by-step explanation:
The total number of sums (not distinct) is 
, because we're removing without replacement.
Count the sums that fit the stipulation (sum 
5):
There are 8 sums that work. Therefore, the desired answer is 
R=16
J=32
20+40(which is 20×2)=60
20-4=16
16×2=32
Answer:
D if im wrong im sorry
Step-by-step explanation:
combining like terms in a polynomial is adding or subtracting together terms that have the same degree in the exponents.
example. 3x^3 + 5x^6 + 2x^3 +7x + 9x^6
= 7x + 5x^3 + 14x^6
Answer:
34
Step-by-step explanation:
We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.
180=(x+12)+100+x
We can remove the parentheses and combine x plus x to 2x.
180=100+2x+12
100+12=112
so
180=112+2x
-112 -112
68=2x
÷2 ÷2
34=x
