Step-by-step explanation:
Here first open the inner parentheses and use the distributive property,

Answer:14
Step-by-step explanation:First, you can plug in the numbers, so the equation would look like 126=1/2b(18). Since theres 1/2, 1/2 of 18 is 9, so it would be 126=9b. 126/9=14
The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.
<h3>What is the Slope?</h3>
The slope of a line (m) = rise/run = change in y / change in x.
Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:
Slope (m) = (5 - 3)/(2 - 1)
Slope (m) = (2)/(1)
Slope (m) = 2
This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3
