Answer:
yes
Step-by-step explanation:
bc 20/2 is another way to fimd it which gets you 10
7x - 9 = 28 + 4x - 4
7x - 4x = 28 - 4 + 9
3x = 33
x = 11
Answer:
The expression equal to 2x^(2)+8 is:
First option (2x-4i)(x+2i)
Step-by-step explanation:
If we multiply
(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)
(2x-4i)(x+2i)=2x^(1+1)+4xi-4xi-8i^(1+1)
Simplifying:
(2x-4i)(x+2i)=2x^2-8i^2
and i^2=-1, then:
(2x-4i)(x+2i)=2x^2-8(-1)
Multiplying:
(2x-4i)(x+2i)=2x^2+8
I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.
If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.
After that just check your answer by seeing if the mean of all the numbers is the same.
