The length of CD is 7-3=4.
Therefore, if we dilate by a scale factor of 3, the length is 4(3) = 12
hello i just took the test the answer is 26
Answer:
you may
2x+15+4x+21=90 simplified is 6x+36=90
m<a=33º
m<b=90º
m<c=57º
Step-by-step explanation:
6x+36=90
6x=54
x=9
2(9)+15=33
4(9)+21=57
The first step for finding y is to divide both sides of the equation by 9.
9y ÷ 9 = 2x ÷ 9
When dividing 9 by 9 you must remember that any expression divided by itself equals 1.
y = 2x ÷ 9
Now write 2 ÷ 9 as a fraction.
y =
x
This means that the answer to your question is that y =
x.
Let me know if you have any further questions.
