v = h * l * w OR v = h * a

a = l * w

1,200 = h * 80

1200/80 = 15 units

-2(4r - 6) Mathhhhhhhhh pls

Answers

Answer: -8r+12

Step-by-step explanation:

Answer:   -8r + 12

============================================

Explanation:

The outer term -2 is multiplied by each term inside

-2 times 4r = -8r-2 times -6 = 12

Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.

I used the distribution property, also known as the distributive property.

That says a*(b-c) = a*b - a*c

In this case, a = -2, b = 4r, and c = 6.

Can someone pls describe how to do this.. and thank you

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

What is Graph?

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

Daryll is given $30 and spends $1.25 per day on basketball cards.

Larry is given $2 and saves $1.25 per day.

So, to find the same day for both from the graph.

We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.

Hence, the boys have $16 on 11th day.
