(7,4) they’re both positive numbers
        
             
        
        
        
Answer:
I think that the altimeter would read as '0'. Positive readings would show that she was above sea level and negative readings we would show that she was below sea level. I hope that this helps

Answer:</h2>

<h2>
Step-by-step explanation:</h2>
A trapezoid is a quadrilateral where at least one pair of opposite sides are parallel. In a trapezoid, the both parallel sides are known as the bases of the trapezoid. So we have two bases, namely,  . Also, the height
. Also, the height  of the trapezoid is the length between these two bases that's perpendicular to both sides. So the area of a trapezoid in terms of of
 of the trapezoid is the length between these two bases that's perpendicular to both sides. So the area of a trapezoid in terms of of  is:
 is:

Since:

The area is:

 
        
        
        
Answer:
D or the last one. 
Step-by-step explanation:
Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.
