For this case we have the following multiplication:

5 * 216

We can rewrite this multiplication in the following way:

5 * (200 + 16)

From here, we apply the distributive property.

We have then:

(5 * 200) + (5 * 16)

Therefore, Jack's strategy is:

Write the number in an expanded form and then apply the distributive property.

The <em>correct answer</em> is:

He used the distributive property.

Explanation:

To rewrite a product using the distributive property, break one of the numbers up into two smaller, easier to multiply numbers. In this problem, Jack broke 216 into (200+16). He then multiplied by 5:

5(200+16)

Using the distributive property, we multiply the number outside by both factors inside:

5(200) + 5(16) = 1000+80 = 1080

This makes the number easier to multiply quickly.

What is the value of x2+9x+20 when x could be -5, -3 or -6
ANTONII [103]

Answer:

Step-by-step explanation:

You should use a ^ to indicate an exponent. x^2 is the same as x².

x² + 9x + 20

Replace the x with (-5).

(-5)² + 9(-5) + 20 = 25-45+20 = 0

Then do the same with x = (-3):

(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2

You can do x = (-6)
