Answer:
what are the numbers shown?
Answer:
4 times 5 = 20, and 20 is... well.. 20
Step-by-step explanation:
When a number has another number in parentheses by it, it means you multiply the numbers together. So 4(5) is the same as 4 times 5, which equals 20
Answer:
x = 3
Step-by-step explanation:
x*6 = 6x, then we divide both sides by 6 to get x alone. 6x/6 = 18/6.
x = 3, 18 divided by 6 is 3.
[x-(-1+i)][x-(-1-i)]
[(x+1)-i][(x+1)+i]
(x+1)²-i²
(x²+2x+1)+1
x²+2x+2
so the answer is 2x
