The dimensions of a rectangle are √50a^3b^2 and √200a^3. What is the students error?

The student incorrectly simplified .

Thus, option D is correct.

Step-by-step explanation:

The formula to determine the Perimeter of a rectangle of width w and length l is expressed as:

In other words, the perimeter can be determined by multiplying the length and width by 2 and adding the result.

In our case, the dimensions of a rectangle are  and  .

Here is the student's solution:

The student made an error in calculating , because are not like terms.

Hence, can not be simplified to

Therefore, the student incorrectly simplified .

Thus, option D is correct.

Here is the correct Solution:

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
