Answer:
20
Step-by-step explanation:
Plug in -4 for n:
(-4)^2 - (-4) = 16 + 4 = 20
Answer: 36
Step-by-step explanation:
From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.
When there are 90 cars sold in a month, the number of silver cars that were sold would be:
= [4 / (4 + 6)] × 90
= 4/10 × 90
= 4 × 9
= 36 silver cars
Here it is…
Simplifying
C = 25h + 50
Reorder the terms:
C = 50 + 25h
Solving
C = 50 + 25h
Solving for variable 'C'.
Move all terms containing C to the left, all other terms to the right.
Simplifying
C = 50 + 25h
Answer:
y=-2x+13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-3)/(4-5)
m=2/-1
m=-2
y-y1=m(x-x1)
y-3=-2(x-5)
y=-2x+10+3
y=-2x+13
Actually Welcome to the concept of Equilateral triangles.
Since, from the name itself, equilateral triangles have all sides and angles equal.
Hence the correct answer is
==> D. All sides are the same length.
