X subtracted from y means y-x
h+3 subtracted from 6h+1 means 6h+1-(h+3)
din't forgtet to distribute invible -1
6h+1-1(h+3)=
6h+1-h-3=
6h-1h+1-3=
5h-2
Answer:
Step-by-step explanation:
a) substitute t = 1 in the expression
3 - 2t = 3- 2*1
= 3 - 2
= 1
b) substitute t = 4 in the expression
3 - 2t = 3 - 2*4
= 3 - 8
= (-5)
Answer:
All angles are 60 degrees
Step-by-step explanation:
Because all sides are equal , all angles are equal also.
180 / 3 = 60
Answer:
96π cm²
Step-by-step explanation:
Use the formula for the surface area of a cylinder:
A = 2πrh + 2πr²
Plug in the height and radius, and solve:
A = 2π(4)(8) + 2π(4)²
A = 2π(32) + 2π(16)
A = 64π + 32π
A = 96π
So, the surface area of the cylinder is 96π cm²
