Answer: The Given sequence is 9, 10, 11, 12

We need to find the expression to describe the sequence.

Let  be the  term of the sequence.

Let n represent the position of the term.

Let a be the first term in the sequence.

and d be the common difference between the sequence

Hence the expression to find the above sequence is given below;

when n=1 d= 1 a = 9

when n=2 d= 1 a = 9

when n=3 d= 1 a = 9

when n=3 d= 1 a = 9

Hence the expression is

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex](4x -3)(2x^2 -7x + 1)[/tex] is [tex]8x^3 - 34x^2 + 25x - 3[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is obtained as:

[tex](4x -3)(2x^2 -7x + 1) = 4x(2x^2 - 7x + 1) -3(2x^2 - 7x + 1)\\(4x -3)(2x^2 -7x + 1) = 8x^{1 + 2} - 28x^2 + 4x - 6x^2 + 21x - 3\\(4x -3)(2x^2 -7x + 1) = 8x^3 + (-28-6)x^2 + (4 + 21)x - 3\\(4x -3)(2x^2 -7x + 1) = 8x^3 - 34x^2 + 25x - 3[/tex]

Thus,

The product of  [tex](4x -3)(2x^2 -7x + 1)[/tex] is [tex]8x^3 - 34x^2 + 25x - 3[/tex]

Leonardo purchases goods at the store of 30.894 and paid $30. 89. Leonardo did not pay enough.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

Leonardo makes the following purchases at the

Store: 1 backpack for $16.89, 5 spiral notebooks for $1.19, each 1 pack of mechanical pencils for $3.68, 2 packs of lead refills for $1. 88 each

The total amount of these items is,

[tex]P=1\times16.89+5\times1.19+1\times3.68+2\times1.88\\P=16.89+5.95+3.68+3.76\\P=30.28[/tex]

The coupons are applied after tax, and the sales tax is 5% of the purchase. Thus the amount will be,

[tex]P=30.28+30.28\times\dfrac{5}{100}\\P=31.794[/tex]

Leonardo has 2 coupons, each for 45 cents off on the purchase of a pack of lead refills. Thus, the sum become,

[tex]P=31.794-2\times0.45\\P=30.894[/tex]

Now, Leonardo paid $30. 89 therefore, he did not pay enough.

Answer:

Interest to be paid will keep on reducing each month

Step-by-step explanation:

due to reduction of the principal amount. As a result the net interest output will be higher for a borrower who carries balance for the whole year compared to one who pays offs monthly.

Answer:

Who is paying is not as important as the interest rate. Either way, a lower rate will benefit the person who has the bill.

Step-by-step explanation:

since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 15 = 6.6666666666667

Once we have that, we can multiple both the numerator and denominator by this multiple:

6 x 6.6666666666667/15 x 6.6666666666667

= 40/100

Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.

We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:

6/15 = 0.4

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.4 x 100 = 40%

And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.

Answer:

40%

Step-by-step explanation:

6/15 = 0.4 = 40%

All these mean the same them, but what we are looking for is a percentage, which is 40%.

Answer:

True, it is a solution

Step-by-step explanation:

First, let’s distribute 1/3 to x and 4

When we do this, we get:

1/3x+4/3=20

Now, we can solve the equation!

Subtract 4/3 from each side of the equation to isolate the x

We now have 1/3x=18 2/3

Now we divide 1/3 on each side to isolate the x (this is the same as multiplying by 3/1 on each side)

This gets us to x=56

So it is true

Answer:

x = 49/5 (fraction)

Step-by-step explanation:

Add and subtract the numbers: -15 + 52 =37

6x+37=11x-12

Subtract 37 on both sides:

6x+37-37=11x-12-37

Simplify:

6x=11x-49

Subtract 11x from both sides:

6x-11x=11x-49-11x

Simplify:

-5x=-49

Divide both sides by -5

-5x/-5=-49/-5

= 49/5

Step-by-step explanation:

There is not enough information given in this diagram to provide values for the marked angles. In order to solve the problem, we must assume some relation between those angles.

If they are equal, then ...

  9x -22 = 6x -7

  3x = 15 . . . . . . . . . . add 22-6x to both sides

  x = 5 . . . . . . . . divide both sides by 3
