12 - 3x + 4 ( 10 - 2^3 )
12 - 3 ( 2/3 ) + 4 ( 10 - 2^3 )
12 - 2 + 4 ( 10 - 8 )
12 - 2 + 40 - 32
10 + 8
18
The answer is option (c) 7xy^2-2xy^2
the sum of all interior angles in a polygon is
180(n-2)
n = number of sides
now, this one is a Heptagon, 7 sides, so the total of interior angles is 180(7-2) = 900.
Answer:
a = 9h + nb
Step-by-step explanation:
1) Variables:
a=total amount earned
h=hours worked in one week
n=number of items repaired
b=bonus amount for each item
2) He earns $9.00 an hour plus a bonus for each item repaired.
=> he earns 9 times the number of hours plus value of the bonus times the number of items repaired
=> a = 9h + nb
