Answer:1197m³
Step-by-step explanation:
The first error made by Cai in his proof was: the use of an invalid reason to <em>justify </em>the congruence of a pair of sides or angles. (<em>Option A</em>)
<em><u>Recall:</u></em>
- If two triangles have two pairs of congruent sides and a pair of included side that are congruent, both triangles are considered congruent by the Side-Angle-Side Congruence Theorem (SAS).
<em>△FGH and △HIJ are shown in the diagram attached below. Also, the diagram shows the </em><em>proof </em><em>of Cai.</em>
<em />
The first error that can be noted is that Cai the reason given for stating that is false and invalid.
<HFG and <JHI are corresponding angles which makes them congruent. They are not alternate interior angles.
- Therefore, the first error made by Cai in his proof was: the use of an invalid reason to <em>justify </em>the congruence of a pair of sides or angles. (<em>Option A</em>)

Answer:
m is the slope of the line
b is the y-intercept
Step-by-step explanation:
We are given the form of a linear equation in slope intercept form as;
y = mx + b
Now, the meaning of each term of the equation is;
m is the slope of the line
b is the y-intercept
