72/8 = 9
“/“ means division by the way.
Plug the -4 into equation
f(-4) = 5(-4) -3
multiply 5•-4= -20
then subtract -20-3
when you have two negatives you add
= -23
Answer:
40
Step-by-step explanation:
Find the other missing angle, which is supplementary to 100 first.
Supplementary angels are a sum of 180
The missing angle is 180-100 = 80
Now use that to find missing angle x
All angles in the triangle have a sum of 180
180 = 60+80+x
180-60-80=x
40 = x
The volume of a cylinder is the area of the circular face times the length of the cylinder.
the area of a circular face is

hence the volume is

the Length "L" is 36 in
the diameter "d" is 3 in
Answer:
The area of this triangle is.. 
Step-by-step explanation:
6 x 10 divided by 2 = 30
