I am thinking B, because if you think about it you would write it as x+ 8 because he first got x and then he added 8 more to that x and then they tell you how much they recived in those days if you multiply the like in answer D you will get to much and their askign for the total of teh 2 days so you would add them,... Hope this helped
Answer:

Step-by-step explanation:
Given
Quadratic equation is

Roots of the quadratic equation
are

So, for the given equation roots are

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.
Unfortunately I don't really know what to do from here, but I hope it helped at least a little.
The correct answer is 1/8.
80% of 90 is 72 and half of 140 equals 70. So 80% of 90 is bigger
