Answer:
c) 28
explanation :
In this sequence:
a1 = 2
a2 = 4
a3 = 6
a4 = 8
a5 = 10
and so on...
then
the sum from a2 to a5 is:
a2 +a3 + a4 + a5 = 4 + 6 +8 + 10 = 28
Answer:
use a calculator or sum im so sorry im only in 7th grade
Step-by-step explanation:
The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.
A=1/2(9)(4)
Multiply to get 18 square cm, which is choice D.
It would value to -15 because you just need to plug in the (-4) into the X

Answer: D) Ray NM</h3>
Ray NP starts at point N as the fixed endpoint and goes off forever in the direction of point P.
The opposite would be to turn 180 degrees and go the other way. So we start at N and instead go off forever toward point M. In either case, the starting point is still the same (point N).
When naming rays, the order is important. Ray NM is different from ray MN. This is because the first letter is the fixed end point (that doesn't go off forever in one direction).
