If 43 liters of water are enough to water 25 of the plants in the house, how much water is necessary to water all the plants in the house? Write a multiplication equation and a division equation for the situation, then answer the question. Show your reasoning.

Answers

If you meant 25% of the plants in the house, so that could also be shown as 1/4 or a quarter of the plants in the house so that means that four times 43 litres would be needed to water four times these plants.

4 x 43 = 172L

Your answer is 172 litres :)

(If you meant 25 plants I would be able to help you if you could tell me how many plants were in the house altogether)

Answer:

6 cm

Step-by-step explanation:

Formula for Area of A Square Is: [tex]A = s^2[/tex]

s - given side

We would need to take the square root of 36 to get the side length.

[tex]36 = s^2\\\\\sqrt{36} = \sqrt{s^2}\\\\\boxed{6 = s}[/tex]

Answer:

276 guests

Step-by-step explanation:

Let the number of guests be n.  We are to find the value of n.

Then (1/3)n + (5/12)n + 69 = n, or

                (9/12)n + 69 = n or (12/12)n

Solving for n, we get    (3/12)n = 69, or (1/12)n = 23, or n = 12(23) = 276

There were 276 guests at the wedding.

Check:  Does (1/3)(276) + (5/12)(276) + 69 work out to 276?  yes

What is quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

In the given functions which are in the form of ax²+bx+c=0 such functions are considered as quadratic function.

The highest power of the variable x should be two.

f(x)=5² is not a quadratic function.

f(x) = 2/x is not a quadratic function.

f(x)=3(x-4)(x+3)

Let us simplify the function

f(x)=3(x²+3x-4x-12)

=3(x²-x-12)

f(x)=3x²-3x-36

So f(x)=3(x²+3x-4x-12) is a quadratic function.

Hence, Option C is correct, f(x)=3(x-4)(x+3) is a quadratic function.
