Answer:
3h²
Step-by-step explanation:
factor or breakdown 3h² : 3 * h * h
factor or breakdown 3h³ : 3 * h * h * h
Now, we can see that 3 * h * h is common so 3h² is the gcf.
Answer:
Step-by-step explanation:
the system of equations is:
First, we multiply the second equation by -9:
and now we add this to the first original equation:
we have eliminated the y variable, so we can solve for x:
with this value of x, we substitute it on the second of the original set of equations to find the value of y:
the answer as an ordered pair is:
Answer:
18.
Step-by-step explanation:
6 * [13 - 2(4 + 1)] = 6 * [13 - 2(5)] = 6 * (13 - 10) = 6 * 3 = 18
Hope this helps!
∠C = 180° - 45° - 65°
∠C = 70°
b/sin B = c/sin C
b/sin 65° = c/sin 70°
b = c/sin 70° × sin 65°
b = 20/0.9397 × 0.9063
b = 19.289
b = 19.3
