Answer:
8x
Step-by-step explanation:
Because you are adding the (x+3) there you can immediately you the association property to simplify
(2x + 5x + x) + (3 - 3)
8x + 0 =
8x
Answer:
b
Step-by-step explanation:
cause it a circle and it will need a little more then the number it is
Answer:
For all x, x element of A and x element of B.
Answer:
x =8
y = 4sqrt(2)
z = 4sqrt(2)
Step-by-step explanation:
The easiest one to calculate is x
If it is a 45 -45-90 degree triangle then AB = BC=x
Since AB =8 then BC =8 and x=8
The next easiest to calculate is z
If it is a 45 -45-90 degree triangle then AD = BD=z
Using the Pythagorean theorem
z^2 +z^2 = 8^2
2z^2 =64
Divide by 2
x^2 = 32
Taking the square root of each side
z = sqrt(16)sqrt(2)
z=4sqrt(2)
Finally, we can find y
If it is a 45 -45-90 degree triangle then BD = DC
BD =z =4 sqrt(2) = DC = y
Therefore y =4 sqrt(2)
Answer:
alternate int. <s of parallel lines
Step-by-step explanation:
We are told that lines r and s are parallel.
Lines r and s are curt by transversal line m.
Theorem:
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Angles 2 and 11 are alternate interior angle, so they are congruent.
Answer: alternate int. <s of parallel lines
