Answer:
5 units
Step-by-step explanation:
To solve this we can use pythagoras theory:
- a² + b² = c², where c is the diagonal
- 3² + 4² = c²
- 9 + 16 = 25
- c² = 25, so c = √25
- c = 5
Hope this helps!
Answer:
C
Step-by-step explanation:
We know it's direct variation using the direct variation equation.

Where k is the constant.
Since 7 times x is the y values, 
Now we can substitute 7 into k of the direct variation equation.
