Answer: 6 hours or 360 minutes
Step-by-step explanation:
First find out how long it takes to deliver to one house.
Convert hours to minutes.
2.5 x 60 = 150 minutes total
Divide to find the time per house
150 minutes / 130 houses = 1.15 minutes per house
Now multiply this rate by the number of houses (312).
312 x 1.15 = 360 minutes
If you want it in hours then divide by 60.
360/60 = 6 hours.
Answer:
yes
Step-by-step explanation:
I think the correct answer from the choices listed above is the distributive postulate. The expression 3x + 3 = 3(x + 1) is an example of a distributive postulate. It <span>says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately. Hope this answers the question.</span>
Ax^2 + bx + c = 0
x^2 - 5x = 14
x^2 - 5x - 14 = 0
a = 1
b = -5
c = -14
Answer:
No
Step-by-step explanation:
We have to find that a quadratic polynomial equation with real coefficient can have one real solution and one complex solution.
quadratic equation is given by

It can be written as the product of linear factors

Where
are solutions of the given polynomial equation.
No , a quadratic polynomial equation can not have one real solution and one complex solution because complex root are always in paired not a single.
A quadratic equation have two roots only.
If a quadratic equation have complex root then the equation have both complex root .
If a equation have real root then it have both real.
Therefore, a quadratic equation can not have one real and one compelx solution.
