5,7 and 8 are right angles, and 6 is an acute angle this is because of u look at 9 and 10 you can see a little box looking thing under the h and if u do that to all of them 5, 7 and 8 can fit the little box but 6 you can’t because it is an acute angle. Hope this helped!
I think its B Because u have the total of pencils and how much they cost now u need to how know many pins you have to know how many they have in total
20 and 22
You would create an equation that would simulate this situation and solve for x to find the first even integer. Then add 2 to x to find the second even integer.
First you distribute the -12 to the (x+5) getting 144=-12x-60.
Next you add 60 to each side getting 204=-12x
Then you divide each side by -12 getting -17=x, which is the answer.<span />
