The answer is B, because the x-axis is the domain, and the max for the domain in 240, so it would have to be less than or equal to 240, but greater than or equal to 0.

Xiao’s teacher asked him to rewrite the sum 60+90 as a product of GCF of two numbers and A sum . xiao wrote 3(20+30.what mistake

maks197457 [2]

The first thing we must do for this case is find the factors of each of the numbers.

We have then:

60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Therefore the GCF is given by:

$GFC = 30$

So, by rewriting the sum we have:

$60 + 90 = 30 (2 + 3)$

The error is not having written the GCF multiplying.

Answer:

Xiao did not write the sum as the product of GCF and the sum of two numbers.

The correct expression is:

$60 + 90 = 30 (2 + 3)$
