Answer:
x = 5
Step-by-step explanation:
ABC is an isosceles triangle
So
<A = <C = 73
<B = 180 - 2 * 73
<B = 180 - 146
<B = 34
Given <B = 6x +4
So
6x + 4 = 34
6x = 30
x = 5
Basically
Circumference = 2 * pie * radius
To get the radius u need to measure the circles distance. For example I measured a circular mirror and the distance was 10cm. This is the diameter. To get the radius I’ll divide by 2 because the radius is from the centre of the circle to the edge. So, 10 divided by 2 = 5cm. The radius is 5cm. Now,
Circumference = 2 * pie * r
r = 5. Pie = 3.14
Circumference = 2 * 3.14 * 5
= The answer
****pie is always 3.14
I hope you understood
Answer:
9
Step-by-step explanation:
For 4x/x+3, just cancel the x to get 4+3=7
For -4x/x+6, cancel the x to get -4+6=2
7+2=9
Hope this helps
