The area of a rectangle is the multiplication of its width times its length, that is:
area = width*length
We have to write as an equation the information about the relationship between the width and the length, they say the width is 1/4 of the lenght, this is:
width = lenght/4
now we substitute the data we have:
area = width*length
144 = (length/4)*length
length^2 = 4*144 = 576
the length is raised to the second power because we had to multiply length*length, so to solve the last equation we had to take the square root to both sides:
length = √576
<span>length = 24
</span>so the length of the banner is 24 feet, and we know that:
<span>width = lenght/4
</span><span>width = 24/4
</span>width = 6
so the width is 6 feet
Here's how you would do that , 162.3
Answer:
8
Step-by-step explanation:
1hour 20 min = 80 min then divide 80 by 10
Answer: Yes
Explanation: a statement that the values of two mathematical expressions are equal (indicated by the sign =).
Two values (6 and 3) are being brought together for another value represented by the = symbol making this an equation
First differences are ...
41 -39 = 2
43 -41 = 2
45 -43 = 2
These are all the same, so 2 is the common difference of the arithmetic sequence beginning with 39.
The Nth term is
The problem statement seems to ask for the 10th term and for a15. Here they are.
