<h3>
Answer: The year 2020</h3>
Explanation:
x is the number of years since 1988
x = 0 represents the year 1988
x = 1 is the year 1988+1 = 1989
x = 2 is the year 1988+2 = 1990
etc
x = 32 is the year 1988+32 = 2020
 
        
        
        

 
<h3>x = 21/5</h3>
Step-by-step explanation:
<h3>___________________________</h3>
<h3>Given →</h3>
5x:9 = 7:3
<h3>So,</h3>
→ 5x/9 = 7/3
→ x = (7 × 9)/(3 × 5)
→ x = 21/5

Answer:
A
Step-by-step explanation:
If all of the dimensions of the tank are doubled, since we live in three dimensions, the volume of the new tank will be  times as large.

Let us try and solve it analytically. We have that the side=x+3  together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that 

. This yields 

which yields s^2=2x+7, hence a) is the correct answer.
 
        
        
        
-2
y2-y1/x2-x1
take the y coordinate of the second pair of coordinates and subtract it by the y coordinate of the first pair, then take the x coordinate from the second pair of coordinates and subtract it from the x coordinate from the first pair. then put your answer from the y coordinate over the answer from the x coordinates. 1 - 13 / 8 - 2, then you get -12/6, which simplifies to 2. 
Hope this helps :)
