Answer:
15" by 10"
Step-by-step explanation:
Use a proportion.
10'/5" = 30"/x
10x = 5 * 30
10x = 150
x = 15"
10'/5" = 20'/y
10y = 5 * 20
10y = 100
y = 10"
Answer: 15" by 10"
You need to use the distance formula


so the distance between points (5,-2) and (-3,8) is

which won't simplify so it stays as is
Answer is below..............
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
