Answer:
A.2
Step-by-step explanation:
We know that |x|² = 13 and x = 3+bi:
(3+bi)² = 13
3² + b² = 13
9 + b² = 13
Subtract 9 from each side:
9 + b² - 9 = 13 - 9
b² = 4
Take the square root of each side:
√b² = √4
b = 2
To make this easier the answer is, "y = 2x + 5"
Answer:
x = -5
Step-by-step explanation:
Angles "50" and "x+55" are alternate interior angles which means that they are the same.
So 50 = x + 55
That leaves you with x = -5
Answer:
10b+4
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we would simply group together the similar terms!
13b+8b=21b-11b=10b
10-6=4
10b+4 is your final answer

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!
Answer:
u(12-v)
Step-by-step explanation:
12u and -uv both have a factor of <em>u </em>in common, so we can pull it out to give us the factored expression u(12-v).
<em>Note on factoring:</em>
<em>Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.</em>
