If your just looking for x then x=2
The answer is b.
Because you multiply (5•12)
The question is related to integration and we have to used the following formula





Answer:
C
Step-by-step explanation:
Using Pythagoras' identity to determine if the triangle is right
The square of the longest side should equal the sum of the squares on the other 2 sides, that is
QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )
QS = 
Δ QRS is not right as QS would have to be 
Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
