Find g(x+3) if g(x) = 2x² – x

Answers

Answer 1
You need to plug in (x+3) where ever there is an x.

So your equation should look like:

G(x+3)= 2(x+3)^2-(x+3)
2(x+3)^2-(x+3)
Simplify
Final answer: 2x^2+11x+15

When x is added to its square, the total is 30. Fond the value of x.
(With solution please)

Answers

Answer:

[tex]x=\frac{30}{(1+x)}[/tex]

Step-by-step explanation:

step one:

This is a word problem, we need to translate is it to mathematical terms before we solve

"When x is added to its square, the total is 30"

step two:

[tex]x+x^2=30[/tex]

[tex]x+x^2=30\\\\x(1+x)=30\\\\[/tex]

step three:

divide both sides by 1+x we have the value of x as

Point R is on line segment QS. Given QS = 16 and QR = 9, determine the length RS.

Answers

Answer:

The length RS = 7

Step-by-step explanation:

Here, we are interested in determining the length of RS

Let’s have the line segment arranged as follows;

Q R S

where QR = 9 and QS = 16

From the arrangement, we can deduce that;

QS = QR + RS

Thus;

RS = QS - QR

RS = 16 -9

RS = 7

the perimeter of a square can be found using P = n + n + n + n, where n is the length of one side of the square. Which equation could also be used to find the perimeter of a square

Answers

Answer:

P = 4n

Step-by-step explanation:

P = n + n + n + n

If you combine all the like terms you end up with:

P = 4n

The equation to find the perimeter of a square can also be expressed as 4n, where n is the side.

What is Square?

A square is a two dimensional figure which has four vertices, four sides and four angles.

Perimeter of a geometrical figure is the sum of the lengths of the boundary of shape.

Given that n is the length of one side of a square.

Perimeter is the sum of the side lengths.

Since a square has four sides,

Perimeter = 4 times the length of side

                 = 4n

Hence the perimeter of a square can also be expressed as 4n.

1 sack of flour contains 21 cups. It takes 3 cups of flour to make a batch of cookies. How many batches of cookies can you make with TWO sacks of flour?

Answers

the answer would be 14...
1 sack = 21 cups.
so 2 sacks would equal 42 cups because 21x2= 42
and it takes 3 cups of flour to make ONE batch of cookies. So 42 divided by 3 is 14. And that’s how you get your answer.

Answer:

14 batches

Step-by-step explanation:

If 1 sack of flour = 21 cups, and 1 batch of cookies need 3 cups, all you have to do is find out how many batches can be made with 1 sack and double the number:

3 × _ = 21

21 ÷ 3 = 7

7 × 2 = 14

You can make 14 batches of cookies with 2 sacks of flour.
