Answer:

No solutions

Step-by-step explanation:

In this question, you would be solving for x.

Solve:

5 + 2(3 + 2x) = x + 3(x + 1)

Use the distributive property.

5 + 6 + 4x = x + 3x + 3

Combine like terms.

11 + 4x = 4x + 3

Subtract 4x from both sides.

11 = 3

Since we don't have an "x value", there are no solutions.

"No solutions" would be your answer.

Answer:

C. 3h - 6

Step-by-step explanation:

The simplified expression for the given algebraic expression [tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}[/tex] is [tex](a+b)(a-b)(c+2d)(c-2d)[/tex]

As per the question statement, we are given an algebraic expression

[tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}[/tex] and we are supposed to solve and simplify it.

Solution:

[tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}\\c^{2} (a^{2} -b^{2})-4d^{2}(a^{2} -b^{2})\\(a^{2} -b^{2})(c^{2}-4d^{2})\\(a^{2} -b^{2})(c^{2}-(2d)^{2})\\[/tex]

Have used Distributive property for solving and simplifying the above algebraic expression.

Now using the property, [tex]a^{2} -b^{2} =(a+b)(a-b)[/tex]

We get,

[tex](a+b)(a-b)(c+2d)(c-2d)[/tex]

Therefore [tex](a+b)(a-b)(c+2d)(c-2d)[/tex] is our required answer.

Answer:

Lucy cuts 4 squares with side length x in. from the corners of a 6 in. by 9 in. cardboard rectangle. She folds the remaining cardboard to make a tray that is x in. high. Write and simplify a polynomial function for the volume V

Step-by-step explanation:

9v

The polynomial function for the volume V of the tray in terms of x will be;

⇒ 4x³ - 30x² + 54x

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

Lucy cuts 4 squares with side length x inch from the corners of a 6 inch by 9 inch cardboard rectangle.

She folds the remaining cardboard to make a tray that is x inch high

Now,

By the give condition we get;

Length of tray = 9 - 2x

Width of tray = 6 - 2x

Height of tray = x

So., The volume of the tray is expressed as;

Volume = x (9 - 2x) (6 - 2x)

             = x (54 - 18x - 12x + 4x²)

             = x (54 - 30x + 4x²)

             = 4x³ - 30x² + 54x

Thus, The polynomial function for the volume V of the tray in terms of x will be;

⇒ 4x³ - 30x² + 54x

Given:

Length of a carton = [tex]2\dfrac{2}{3}[/tex] feet

Width of a carton = [tex]1\dfrac{1}{8}[/tex] feet

Height of a carton = [tex]1\dfrac{1}{5}[/tex] feet

To find:

The volume of the carton.

Solution:

We know that, volume of the carton is

[tex]V=length\times width \times height[/tex]

Putting the values, we get

[tex]V=2\dfrac{2}{3}\times 1\dfrac{1}{8} \times 1\dfrac{1}{5}[/tex]

[tex]V=\dfrac{(2\times 3)+2}{3}\times \dfrac{(1\times 8)+1}{8} \times \dfrac{(1\times 5)+1}{5}[/tex]

[tex]V=\dfrac{8}{3}\times \dfrac{9}{8} \times \dfrac{6}{5}[/tex]

Taking LCM, we get

[tex]V=\dfrac{18}{5}[/tex]

[tex]V=3\dfrac{3}{5}[/tex]

So, the volume is [tex]3\dfrac{3}{5}[/tex] cubic feet.

Therefore, the correct option is A.

Answer: The slope is 2/3, y=2/3x+1

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1

Answer:

a = (b + c)/(bx - 1)

Step-by-step explanation:

Given

x= (a+b+c)/(ab)

Solving for a

x = (a + b+ c)/(ab)

abx = a + b+ c

abx - a = b + c

a(bx - 1) = b + c

a = (b + c)/(bx - 1)

Total no of cards = 20

The ratio of animal cards to fruit cards is 2:3

No of animal cards = 20

Solution,

Let there are 2x animal cards and 3x fruit cards. ATQ,

2x+3x = 20

5x = 20

x = 4

Animal cards = 2x

= 2(4)

= 8

Fruit cards = 3x

= 3(4)

= 12

It is also mentioned that, of the cards, 1/3 have bananas on them. It means,

[tex]B=\dfrac{1}{3}\times 12\\\\=4[/tex]

Hence, 4 cards have bananas on them.

The total charges are $197.55.

According to the statement

We have to find that the total charges.

So, For this purpose, we know that the

A equation is an algebraic equation of the shape y=mx+b. involving only a continuing and a first-order (linear) term, where m is that the slope and b is that the y-intercept.

From the given information:

He fumigated 3 rooms in one house, 2 in another, and 4 in an exceedingly third.

Then

Landon Elliott takes charges to fumigate each room = $21.95

He fumigated rooms on Monday  = 3 + 2 + 4 = 9 rooms

His total charges = 21.95 × 9

Answer:

Multiply by 100

Step-by-step explanation:

The equation is given as:

-m + 0.02 + 2.1m = -1.45 - 4.81m

To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.

The decimal coefficients and independent terms are

0.02, 2.1, 1.45, 4.81

Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:

100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)

-100m + 2 + 210m = -145 - 481m

Now all terms have integer coefficients as required.

Answer: p= (-0.10)x + 31

Step-by-step explanation:

m is the slope, and we know that each time they need to drop $0.10 so that is our slope. For the b we just need to get $0.10 times 260 cards that need to sell and add 5 and we get 31. So, the equation is p= (-0.10)x + 31.
