Simplify 1/3(24x-9)+10 ?

First you have to distribute the 1/3. To do this, you can either multiply everything in the parentheses by 1/3 or you can divide it all by 3. I will use the division method, so 24x/3 is 8x and -9/3 is -3, so now the expression is 8x-3+10. You can add together the -3 and the 10 ,  and that is 7, so the answer is 8x+7.
ANSWER: 8x + 7

28.26 meters

Step-by-step explanation:

Hi, to answer this question we have to find the perimeter of the semicircle.

P = (2 π r ) /2 (perimeter of a circle divided by 2)

The length of AB is the diameter of the circle (18 meters)

Since

Diameter (d) = 2 radius (r)

Replacing with the value given:

18 =2r

18/2=r

9 =r

Back on the perimeter formula

P = (2 π r ) /2

Replacing with the values given

P = (2 x 3.14 x 9) /2

P = 28.26 meters
