Answer:
T31= 278
Step-by-step explanation:
formula is Tn=a +(n-1)d
T31= 8+(31-1)9
T31=8+(30)9
T31=8+270
T31=278
Answer:
x=2
Step-by-step explanation:
Step 1: Factor left side of equation.
(3x+1)(x−2)=0
Step 2: Set factors equal to 0.
3x+1=0 or x−2=0
When you move down you subtract and when you move to the right you subtract when your moving up or to the left you add
2:3:4
Shortest is clearly 2
(2×7.5):(3×7.5):(4×7.5)
So the sides are 15 , 22.5 and 30
Perimeter = 15 + 22.5 + 30
Perimeter = 67.5
