Answer:
a=10
b=12
Step-by-step explanation:
Answer:
first option
Step-by-step explanation:
solving the inequality
- 13 > - 5x + 2 > - 28 ( subtract 2 from each interval )
- 15 > - 5x > - 30
divide each interval by - 5 , reversing the symbols as a result of dividing by a negative quantity.
3 < x < 6
since the symbol is < then end values will be an open circle with the values between shaded blue, that is the first graph
Circumference= diameter x pi
12x3.14 = 37.68
The initial expression is:
2x + 4(x - 2)
Replacing x by 3, we get:
2(3) + 4(3 - 2)
6 + 4(1)
6 + 4
10
The value of the expression is 10
