Answer:
2(x-5)(x+9)
Step-by-step explanation:
1) divide whole thing by 2 you get x^2+4x-45
2) from there you can factor it out to (x-5)(x+9)
3) Add the 2 back in on the front
B 3/12 divided by 3/3 = 1/4
I need to see the expressions to answer your question sorry
Eight, because 8+8+8 is twenty-four
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
