Answer:

a) 3x^2 + x - 2

b) 28m

Step-by-step explanation:

a) Since the Area for a normal square is b*l (base x length)

Do the same with this (Using FOIL ig)

(3x - 2) * (x + 1)

3x^2 + 3x - 2x - 2

3x^2 + x - 2

b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a

3(3)^2 + (3) - 2

3(9) + (3) - 2

27 + 3 - 2

30 - 2

28m

Therefore the actual area of this rectangle is 28m

How many solutions does the following system of equations have?
{4x + 6y = 24
2x + 3y = 12

Answers

Answer:

Infinitely many solutions

Step-by-step explanation:

Note that 2(2x+3y=12) is 4x+6y=24, which is the first equation. Therefore, by canceling the equations out, you have 0=0, which means whatever one side equals, the other side ALWAYS equals that.

Yes, the functions are inverses.

Step-by-step explanation:

Hi there!

We're given:

[tex]f(x) = 8x-7[/tex]

[tex]g(x)=\displaystyle\frac{x+7}{8}[/tex]

To solve for g(f(x)), plug f(x) into g(x) as x:

[tex]g(f(x))=\displaystyle\frac{(8x-7)+7}{8}\\\\g(f(x))=\displaystyle\frac{8x-7+7}{8}\\\\g(f(x))=\displaystyle\frac{8x}{8}\\\\g(f(x))=x[/tex]

Because g(f(x)) = x, the two functions are inverses.

A girl can run 6 2/3 metres in one second. How long will it take her to run 100 metres?
HELP PLEASE.

Answers

Answer:

15 seconds

Step-by-step explanation:

How did i get this answer? It is apparent that the girl is capable of running 6 2/3 metres per one second and she must run 100 metres.

First, let's convert 2/3 into a decimal so that it is easier to calculate later. 2/3=0.667 (you can also just do 2 divide by 3 and will end up with the same number)

Now our numbers are 6.667 and 100. Let's divide 100 by 6.667 which estimates to 15

Answer:

It will take the girl 15 seconds to run 100 meters

Step-by-step explanation:

100÷6 2/3 is 15

reverse it to see if your right: 15×6 2/3 is 100

2. Deon wants to find the perimeter of a square with side length 6m - 3. Write two expressions that represent the perimeter, including one expression in simplest form. Perimeter of a square- p = 4(s) or p = s + s + s + s​

Answers

Step-by-step explanation:

The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).

The expressions that represent the perimeter of the square are  p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.

What is perimeter?

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given:

The side of the square is 6m-3 unit.

And all the sides of the squares are equal.

And the perimeter p of the square is,

= the sum of all the sides.

p = 4 x one side.

p = 4(6m-3)

The above expression represents the perimeter of the given square.

Simplifying,

p = 24m - 12

This is the simplest form of the expression.

Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.
