Answer:
Equilateral C.
Step-by-step explanation:
Those tick marks on the sides symbolize that each side is the same length as the ones next to it
BD is parallel to AE because the lines are not touching each other, if you extend the lines if BD and AE they would not touch therefore making BD and AE parallel.
Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Answer:
A. 10. B. -12. C. 3.6
Step-by-step explanation:
You will do this:
a) If x=5 (what about 2x)
=2x times 5 divide by x .That makes the answer 10
b) If y=-3(what about 4y)
=4y times -3 divide by y .That makes the answer -12.
c) If z=1.2(what about 3z)
=3z times 1.2divide by z. That makes the answer 3.6.
