Step-by-step explanation:
HOPE THIS HELPS!
21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21
For this case we have the following multiplication:

We can rewrite this multiplication in the following way:

From here, we apply the distributive property.
We have then:

Therefore, Jack's strategy is:
Write the number in an expanded form and then apply the distributive property.

X - 1 < = 6
x < = 6 + 1
x < = 7.....2nd number line is correct
Answer:
15 sqrt 2
Step-by-step explanation:
Use Pythagorean Theorem
a^2 + b^2 = c^2
15^2 + 15^2 = c^2
225 + 225 = 450
Find prime factors of the sq rt of 450
450 = 2 * 3 * 3 * 5 * 5
15 sqrt 2
