Answer 1

Answer: You have now two polynomials one for length and one for the widht fo the rectangle.

a) The perimeter is the sum of the 4 sides, that is 2 * (length + width) = 2 * (5x^2 + 1 +x^2 + 4) = 2 * (6x^2 + 5) = 12x^2 + 10.

b) The area is length * width = (5x^2 + 1)*(x^2 + 4)

Apply distributive property to multiply:

5x^4 + 20x^2 + x^2 + 4 = 5x^4 + 21x^2 + 4

What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 4x + y - 1 = 0?

Answers

Answer: The required equation of the line is $4x+y=6.$

Step-by-step explanation: We are given to find the equation of the line that passes through (1, 2) and is parallel to the line whose equation is as follows:

$4x+y-1=0~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

The slope-intercept form of the given line (i) is

$4x+y-1=0\n\n\Rightarrow 4x+y=1\n\n\Rightarrow y=-4x+1,$

where, slope of the line is, m = - 4.

Since parallel lines have equal slopes, so the slope of the new line that passes through the point (1, 2) is

m = - 4.

Therefore, the equation of the line will be

$y-2=m(x-1)\n\n\Rightarrow y-2=-4(x-1)\n\n\Rightarrow y-2=-4x+4\n\n\Rightarrow 4x+y=6.$

Thus, the required equation of the line is $4x+y=6.$

y=-4x+6
or if you need it in the original format
4x+y-6=0

Solve the following equations.
1 − log8(x − 3) = log8(2x)

Answers

Answer:

The answer to your question is: 4

Step-by-step explanation:

Data

1 − log₈(x − 3) = log₈(2x)

1 = log₈(x − 3) + log₈(2x)

1 = log₈ 2x(x - 3)

8¹ = 2x(x - 3)

8 = 2x² - 6x

2x² - 6x - 8 = 0

Factorize 2x² - 8x + 2x - 8 = 0

2x(x - 4) + 2(x - 4) = 0

(x - 4) (2x + 2)

x1 = 4 x2 = -2/2 = -1

x2 = -1 is not and answer because there are not negative logs.

Please help! Hi, I'm stuck on a part of this question, we have to solve using Gauss Jordan Elimination: A corporation wants to lease a fleet of 12 airplanes with a combined carrying capacity of 220 passengers. The three available types of planes carry 10,15,20 passengers. How many of each type of plane should be leased?

Answers

Do common sense has anything to do with this question? Because
corporation might forget the arbitrary 12 airplane rule
and have 11 times 20 = 220.
But perhaps they get a discount if all 12 hangars are used!

Playing by the rules of the question:-
Let a, b, c be the aeroplanes that carry
10, 15, and 20 passengers, respectively,

a + b + c = 12
10a +15b +20c = 220

We may rearrange these as
4a + 4b + 4c = 48
2a + 3b + 4c = 44
Now subtract
2a + b = 4

There appear to be 3 options
a = 0, b = 4 which means 220 = 0*10 + 4*15 + 8*20
a = 1, b = 2 which means 220 = 1*10 + 2*15 + 9*20
a = 2, b = 0 which means 220 = 2*10 + 0*15 + 7*20

If you dismiss the ones with zeros it may be that
the expected answer to "How many of each plane" is

One that carries 10, 2 that carries 15, and 9 that carries 20

I have 4 factors three of my factors are 1,2,10 what is my fourth factor

Answers

5. Because 1*10=10 and 2*5=10

Answer

The fourth factor is 5

Explanation

It is given that there are only four factors. Three of them are 1, 2, 10

Here 10 is a factor, so we know that , if 10 is a factor of a number,

the we can write, 10 = 5 x 2, it implies that 5 and 2 are the factors of that number. Here 2 is given. Therefore the fourth factor is 5

The four factors are 1,2,5 and 10
