What is the student’s error?

The answer to the question is 10a√2a(b + 2)

Step-by-step explanation:

To know the student's error, let us calculate the perimeter from the the start.

Dimension of the rectangle is given below:

√(50a³b²) and √(200a³)

Perimeter of a rectangle = 2(L + B) = 2L + 2B

2√(50a³b²) + 2√(200a³)

2 x 5ab√2a + 2 x 10a√2a

10ab√2a + 20a√2a

Factorise

10a√2a (b + 2)

Therefore, the student made an error by adding 10ab√2a and 20a√2a together.

Note: we can not add 10ab√2a and 20a√2a together since b is missing in one of the expression.

Therefore, the answer to the question is 10a√2a(b + 2).

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
