Answer:
4
Step-by-step explanation:
Alright we know the equation AB+BC=AC is the postulate formula given for AC length.
So we do algebraic equation here which would be
(4m-15)+(5m-6)=15
Remove parenthesis
4m-15+5m-6=15
Combine like terms:
9m-21=15
Add 21 to other side
9m=15+21
9m=36
Divide 9
m=36/9
m=4
So the last multiple choice there :)
Answer:
R'(-5, -1) S'(-1, -1) T'(-1,-6)
Step-by-step explanation:
because the triangle is moving to the left, you subtract the number of units from the x coordinates of each vertex of the triangle. becasue the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex.
You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.
