7 <span> more than 3 times a number </span>
<span>more than is code for + </span>
<span>times is multiply </span>
<span>so 7+3n=31 </span>
<span>solve: </span>
<span>3n=24 </span>
<span>n= 8</span>
Y=7/5+6.8
I believe it can a little more than 6.8 but either way this is correct
Answer:
Step-by-step explanation:
AC is the geometric mean. Solve it using this proportion:
Now fill in the values we know:
Cross multiply to get
That means that
AC = 
, which, in decimal form is

The expression for the area of the rectangular swimming pool is given as follows:
A = w² + 100w + 2100.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by the multiplication of these measures, that is:
A = lw.
In this problem, considering the width of 70 meters and a length of 30 meters, plus the floor of w meters, we have that:
Hence the area is given as follows:
A = l x wi = (30 + w)(70 + w) = w² + 100w + 2100.
