The distributive property says that a(b+c)= ab+ac
3(2y-7)= 3(2y)+ 3(-7)
Final answer: 6y-21
Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.
<h3>What is meant by number line?</h3>
- A number line is a graphical representation of numbers on a straight line. A number line has numbers that are sequentially placed at equal distances along its length.
- It can be extended in any direction indefinitely and is usually represented horizontally. A number line is a horizontal line with mathematical increments spaced evenly.
- The numbers on the line will determine how to answer the number on the line. The number's use is determined by the question that goes with it, such as plotting a point.
- The number line is a straight line with divisions at equal intervals, similar to a scale.
Therefore, Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.

Answer:sin240
Step-by-step explanation:
sin300=-(√3)/2
Sin240=-(√3)/2
So sin300 is equivalent to sin240
22 x 85 = (20+2)*85= 20*85+ 2*85 = 1700 + 170 = 1870
