18. It is 18 because when you multiply 2x2 plus 4 x2 plus 2 x3 you get 4 plus 8 plus 6 = 18
Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
X=-13/5
Simplify both sides of the equation, isolate the variable, and then you get your answer.
Speed=distance/time
distance=205.296
time=3.12
speed=205.296/3.12=65.8
answer is 65.8 miles per hour
Answer:
(6,6)
Step-by-step explanation:
The midpoint formula is 
. Substitute (2,10) and (10,2) into this formula and simplify.
