Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0
It is -3.
6x+12=-6
6x=-18
x=-3

<u>Step-by-step explanation:</u>
diameter = 6cm
radius = diameter ÷ 2
= 6 ÷ 2
= 3cm
circumference = 2π × radius
= 2 π × 3cm
= 3π cm
