Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.
If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.
Good luck, and feel free to ask with any questions!
Answer:
C
Step-by-step explanation:
The first part requires the intersection of the two sets, which means only the elements that can be found in both sets.
While the second part requires all the elements in both the sets.
(x+2)^2
This can be rewritten as:
(x + 2)(x + 2)
Multiply everything in the second parenthesis by x.
x^2 + 2x
Multiply everything in the second parenthesis by 2.
2x + 4
Add these equations together.
x^2 + 2x + 2x + 4
Combine like terms.
x^2 + 4x + 4
Hope this helps!
Answer:
25
Step-by-step explanation:
How many units are between 22 and -3? 25. A good way to be able to tell is simply subtract -3 from 22, like so:
22 - (-3) = 25
