4. 2x2 + 4x + 10 = 0
Answer:
Step-by-step explanation:
This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.
a = 2
b = 4
c = 10
You could divide this equation by 2
a = 1
b = 2
c = 5
These three are smaller and easier to calculate. The answer will be the same.
x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)
x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1
x = (-2 +/- sqrt(4 - 20) ) / 2
X = (-2 +/- sqrt(-16) ) /2
x = (-2 +/- 4i ) / 2
x = ( - 1) +/- 2i

The Westminster Widget Company has an old machine that can produce 24 widgets in three hours. Now they have purchased a new
machine that can produce 48 widgets in four hours. Working together, how long will it take the two machines to produce 120
widgets?
9514 1404 393
Answer:
6 hours
Step-by-step explanation:
The old machine produces widgets at the rate of ...
(24 widgets)/(3 h) = 8 widgets/h
The new machine produces widgets at the rate of ...
(48 widgets)/(4 h) = 12 widgets/h
The total rate of production of the two machines is ...
(8 +12) widgets/h = 20 widgets/h
Then the time required to produce 120 widgets is ...
(120 widgets)/(20 widgets/h) = 6 h
Working together, the two machines can produce 120 widgets in 6 hours.

6

Help me please this is due tonight!
Here is a photo of the problem. I’m a little blank on my math tonight, any help is appreciated!
9514 1404 393
Answer:
A
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
__
Using these rules, along with the distributive property, we can simplify the given expression.
[tex]\displaystyle 9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2\\\\=\displaystyle 9a^3b^6(3a^3b^2+7a^2b^2)-(5^2a^{4\cdot2}b^{4\cdot2})\\\\=(9)(3)a^{3+3}b^{6+2}+(9)(7)a^{3+2}b^{6+2}-25a^8b^8=27a^6b^8+63a^5b^8-25a^8b^8\\\\=\boxed{-25a^8b^8+27a^6b^8+63a^5b^8}\qquad\text{matches A}[/tex]

The model represents the quotient of two fractions.
Which equation does this model represent?
A. 5/6 ÷ 1/2 = 1 2/3
В. 2 1/2 ÷ 1/2 = 5/6
C. 5/6 ÷ 2 1/2 = 1/3
D. 2 1/2 ÷ 1/2 = 5
9514 1404 393
Answer:
D.
Step-by-step explanation:
The shaded portion of the three large rectangles is 2 1/2 of them. The divisions indicated by the fractions at the bottom are 1/2. The figure shows that 2 1/2 can be divided by 1/2 with the result that 1/2 goes into 2 1/2 five times.
This description seems to match the equation of choice D.

Riley purchased a 30-day International cell phone plan for use during winter break. There is a one-time fee of $35 and it includes 150 MB of data usage. Each extra megabyte,
or part thereof, of data costs $0.28. Find the cost of the plan if he uses 388 MB of data during the trip.
Answer:
the cost of the plan in the case when 388MB is used is $101.64
Step-by-step explanation:
The computation of the cost of the plan in the case when 388MB is used
Given that
One time fee is $35
And, it involves 150 MB of data usage
Also for the extra megabyte it charges $0.28
So for 388MB, the cost of the plan is
= $35 + 0.28 × (388 MB - 150 MB)
= $35 + $66.64
= $101.64
Hence, the cost of the plan in the case when 388MB is used is $101.64
the sum of two number is 50,and their difference is 30.find the numbers
Answer:
40 and 10
Step-by-step explanation:
if you add them you get 50 and if you subtract them you get 30
Answer:
40 and 10
Step-by-step explanation:
Let the bigger number = x
Let the smaller number = y
x+y=50
x-y=30
(add the equations)
(x+x)+(y-y)=(50+30)
2x=80
x=40
x+y=50
40+y=50
y=10
