The dimensions of a rectangle are 50a’b? and 200a
A student found the perimeter as follows:
What is the student's error?
O The student should not have multiplied each
expression by two.
The student simplified 2/50aºb? incorrectly.
The student simplified 21200a?
incorrectly.
o The student incorrectly simplified
10ab12a + 20a 2a
250ab2+2 200a = 2-5ab 2a +2-10a2a
= 10ab 2a + 20a 2a
= 30ab\2a
DONE

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
