Answer: BC = 54 <kjm=44
Step-by-step explanation:
1st 0ne-
if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)
so
6x=9x-27 (by corresponding parts of congruent Theorem)
-3x=-27
x=9
BC- 9(9)-27= 81-27=54
2nd one-
J bisects KJM
4x+6=3x+10
x=4
3(4)+10= 22
4(4)+6= 22
KJM= 22+22= 44
f(0) means x = 0
Since x = 0 less than 2 so we are using f(x) = -x + 2
Substitute x = 0 into f(x) = -x + 2
f(0) = -0 + 2
f(0) = 2
Answer
2
The graph of 2n^2 +5n -25 opens up because the coefficient of n^2 is positive.
____
The statement 2n^2 +5n -25 = 0 defines two values of n.
Answer:
168
Step-by-step explanation:
If he was faster than Don then it should've taken him less time. So Don would've taken 30 seconds MORE
138+30=168
