Answer:
Option C.
Step-by-step explanation:
Given information:
Number of boxes lifted by Caleb = 14
Number of boxes lifted by Sergio = 12
Let c represent the weight of each box Caleb lifted.
It is given that the boxes that Sergio lifted each weighed 10 lb more than the boxes Caleb lifted. It means
The weight of each box Sergio lifted = c+10
The total number of pounds Sergio lifted is the product of number of boxes lifted by Sergio and the weight of each box lifted by Sergio.
The required expression is 12(c+10). Therefore, the correct option is C.

First, we have to figure out the angles on the interior of the triangles. Since the 90° angle and the angle next to it form a straight line, we know that they are supplementary and add up to 180°. We would then subtract 90° from 180° to find the value of that angle, which comes out to be 90°. Next, since the angle measuring 125° and the angle next to it are supplementary, we would repeat the same procedure: 180° - 125° = 55°. Now that we know the values of two of the interior angles of the triangle, we can solve for the third. The angles of a triangle should add up to 180°, so we can solve for <em>p</em> like this:
90 + 55 + <em>p</em> = 180
145 + <em>p</em> = 180
<em>p </em>= 180 - 145
<em>p</em> = 35
The value of <em>p</em> <em />is 35°.
90 + 55 + <em>p</em> = 180
145 + <em>p</em> = 180
<em>p </em>= 180 - 145
<em>p</em> = 35
The value of <em>p</em> <em />is 35°.
