No the vertex should be at (-3,-2) (I checked on my calculator)
When written in scientific notation, 3,900 = 3.9 x 10^3
Base = 5 * 12 = 60 in^2
Height = 4 in
Perimeter is the sum of all straight
Perimeter = 20 + 16 + 48
Perimeter = 84 in
Perimeter of base = 12 * 2 + 5 * 2 = 34
Answer: 25
Step-by-step explanation:
To solve for UC, you can subtract the length of CN from UN.
UN=40
CN=15
40-15=25
