The matrix represents the vertices of the rectangle after it is scaled by a factor of 3 is,
[ 0 12 12 0]
[ 0 0 12 6]
<h2>We have to determine</h2>Which matrix represents the vertices of the rectangle after it is scaled by a factor of 3?
<h3>According to the question</h3>The vertices of the triangle are
The scale factor is 3.
<h3>The vertices of the triangle are scaled with the factor of 3 so the vertices are get multiplied by 3.</h3>Therefore,
The vertices of the rectangle after scaled by the factor of 3 are,
The vertices of the rectangle after it are scaled by a factor of 3.
Therefore,
The matrix represents the vertices of the rectangle after it is scaled by a factor of 3 is,
[ 0 12 12 0]
[ 0 0 12 6]

Answer:
4 or 4.75
Step-by-step explanation:
first we're going to convert the number into improper fractions.
7=
and 2
=
For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply x2, it'll equal the same number.
So now we have -
, 30-11= 19.
simplified is, 4
.
As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.
I hope this helps you!
