You can only make one triangle because every triangle has 180 degrees so if you add these you get exactly 180 degrees for one triangle
I hope this helps witb you.
Answer:
<em>y = 3x+ 18</em>
Step-by-step explanation:
Given the expression y + 6 = 3(x-4), we are to express in the form y = mx+b
Open the bracket
y + 6 = 3(x-4)
y+6 = 3x-12
Collect the like terms;
y - 3x = -12 - 6
y - 3x = 18
<em>y = 3x + 18</em>
<em>Hence the required equation in slope-intercept form is y = 3x+ 18</em>
The ratio of corresponding sides of the triangle are not in the same proportion, hence they are not similar.
<h3>What are
similar triangles?</h3>
Two triangles are said to be similar if they have the same shape and angles. Also, the ratio of their corresponding sides are to be in the same proportion.
From the image shown, if the triangles are similar, hence:
AB / DE = AC / DF = BC / EF
Hence:
5.6 / 4 = 4.9 / 3.5 ≠ 2.4 / 1.5
1.4 = 1.4 ≠ 1.6
The ratio of corresponding sides of the triangle are not in the same proportion, hence they are not similar.

The mistakes that Joan made are:
- The y-axis does not start from zero.
- The width of the bars are not equal.
- The space between the bars are not equal.
<h3>What is a bar chart?
</h3>
A bar chart is a graph that shows the numerical values of variables represented by the height rectangles of equal width.
In a bar graph, the rectangles must be of equal width and the space between each bars must be equal.
Please find attached an image of the bar chart. To learn more about bar charts, please check: brainly.com/question/18092827
