Hardley didn't make any mistake

Step-by-step explanation:

Given

Step 1: 5×4×1,000

Step 2: 20 * 1,000

Step 3: 20,000

Required

Find Hadley's mistake.

From the highlighted steps above, it is evident that Hardley did not make any mistake when evaluating the given expression.

At step 1, he expanded 4,000 to 4 * 1,000

Step 1:

5×4×1,000

At step 2, he multiplied 5 by 4 which gives 20

Step 2

20 * 1,000

At the last step, which is step 3, he multiplied 20 by 1,000 which gives 20,000 and this is the result of the given expression 5 * 4,000

Step 3

20,000

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
