Answer:

  60 meters

Step-by-step explanation:

The area of Square B is the difference of the areas of squares C and A, so is 225 square meters. The side length is √225 = 15 meters, so the sum of the lengths of the four sides is 4·15 = 60 meters.

The perimeter of square B is 60 meters.

10 more than the quotient of a number and 8 is at least 12. - how would I write this in a "algebraic expression"?
Sonja [21]
X - the number
the quotient of the number and 8 = x/8
10 more than the quotient of the number and 8 = (x/8)+10
10 more than the quotient of the number and 8 is at least 12 = (x/8)+10≥12

\frac{x}{8}+10 \geq 12

The function in the table below shows the relationship between the total number of houses built in an area and the number of mon
professor190 [17]

Answer:

I just did it this is the right answer.

It is nonlinear because the increase in the “Total Houses Built” compared to the increase in the “Months Passed” does not show a constant rate of change.

Can someone help with finding the coordinates and particular PART B.
mestny [16]

Happy New Year from MrBillDoesMath!

Answer:

Part A:

 point   \ coordinates \ quadrant:

 I            (1,2)                  1

 L           (-4,2)                2

 K          (-4,0)                does not belong to any quadrant

 J           (3,-1)                4

 M         (4,-4)                4


Part B:

Point K = (-4,0) lies on the x-axis so reflecting it about the x-axis gives the  same point. In other words, the "reflected" point has coordinates  (-4,0)

 

Part C:

L = (-4,2). Reflecting it about the y-axis gives the point (4,2)


Thank you,

MrB

WITCHER [35]

Answer:

The dependent variable is the rate (3 meters per second) and the independent variable is m (the amount of meters he runs). This is because the rate changes based on the amount of meters he runs.

Simplify 6 plus the square root of negative 80.
Alex777 [14]

The given statement can be written as:

6+√-80

To solve √-80 re-write -80 as -1 * 80

Now √-80 =√-1 * 80

Now we can write it as:

6+ √-1 * √80

We know that √-1 = i

Thus it becomes:

6+ i√80

Now find the square root of 80

80 does not have a perfect square root

Its square root can be found as 80 = 4*4*5

Then,

6+i√4*4*5

Notice that 4 makes a pair.. So we will write it outside the square root

6+1*4√5

We will write it as:

6+4i√5

Thus the correct option is 6 plus 4 i times the square root of 5....
