Answer:
R n S = {20}
Step-by-step explanation:
n in sets means same elements found in the sets which are being compared
Answer:
Answer: Third option is the right answer.
Step-by-step explanation:
First we the write the expression

Now teacher says that the product of these polynomials will result in the sum of 
Now the teacher ask if we put the value of a = 2x and b = 1 then what will be the expression look like.
![(2x+1)\left [ (2x)^{2}+(1^{2})-(2x)(1)\right ]](https://tex.z-dn.net/?f=%282x%2B1%29%5Cleft%20%5B%20%282x%29%5E%7B2%7D%2B%281%5E%7B2%7D%29-%282x%29%281%29%5Cright%20%5D)
=
So third option is looking like our expression.
Answer:
A=8x-8
B=5x+25
A=B(BEING corresponding angles)
8x-8=5x+25
8x-5x=25+8
3x=33
x=33/3
x=11
now 8x-8= 8×11-8
= 88-8
=80
5x+25= 5×11+25
=55+25
= 80
A=B#
Answer:
n = 8
Step-by-step explanation:
10=6+n/2
Switch sides
6 + n/2 = 10
Subtract 6 from both sides
6 + n/2 -6 = 10-6
Simplify
n/2 = 4
Multiply both sides by 2
2n/2 = 4 times 2
n = 8
Hope this helps!
