Liz is using the distributive property to evaluate the expression 27(36) by using friendlier numbers. her work is shown below.

liz’s work

27(36)
step 1

27(3 + 12)
step 2

27(3) + 27(12)
step 3

81 + 324
step 4

405

what was the first error that liz made?
step 1 should have been 27(6 + 30).
step 2 should have been 27(3) + 12.
step 3 should have been 27(30)(12).
step 4 should have been 16,244.

A)Step 1 should have been 27(6 + 30).

Step-by-step explanation:

Given Liz Steps below:

27(36)

Step 1 :  27(3 + 12)

Step 2 :27(3) + 27(12)

Step 3 :81 + 324

Step 4 :405

You will notice that at Step 1, 36 was placed as 3+12 instead of 6+30

The correct workings therefore are:

27(36)

Step 1 :  27(6+30)

Step 2 :27(6) + 27(30)

Step 3 :162 + 810

Step 4 :972

rounding to the nearest thousandth would be 452,000

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
