Answer:
1) 16x -4
2) 7x + 45
Step-by-step explanation:
1 ) 6x + 2(5x -2)
we are going to open the bracket
we have,
6x + 10x - 4
16x -4
4(4x - 1).................................................... simplified
number 2
7x + 3(8+7)
7x +24 + 21
7x + 45........................................................... simplified
so therefore the solution to the first and 2nd question is
1) 16x -4
2) 7x + 45
The circumference of a circle is 2PiR
We have 32Pi, so we can divide 32 by 2 to get the radius
The radius is 16.
The diameter is 2x the radius.
The diameter is 32.
Your answer is B.)
If you have less cavities dentist b would be cheaper but if you only have 1 cavity dentist a would be cheaper
Simplify the numbers
like...
5 10 15 20 25 30 35 40 45 50 55 60
