Step-by-step explanation:
3.75x-5-8.75x+4.5+0.5
=3.75x-8.75x+4.5+0.5-5
=-5x+5-5
==-5x
In the question, they give you the formula for speed...
speed = distance / time
They also give you the distance and the time, so all we have to do is stick them into the equation...
speed = 3 2/3 Km / 1/3 hour
speed = 3 2/3 / 1/3
To divide the fractions, first we need to convert 3 2/3 into an improper fraction
3 2/3 = 11/3
now we multiply 11/3 x the reciprocal of the divisor 1/3. The reciprocal just means flip the numerator and denominator
speed = 11/3 x 3/1
speed = 33/3
speed = 11 Km/hour

Answer: x4+13x2+36=0
Step-by-step explanation:
Let's solve your equation step-by-step.
x4+13x2+36=0
Step 1: Factor left side of equation.
(x2+4)(x2+9)=0
Step 2: Set factors equal to 0.
x2+4=0 or x2+9=0
