The answer is 3. If the lines are parallel then they would have the same slope. :)
1 step: to draw a rectangle around triangle RST, you should
- draw points A(-1,-1), B(-1,3) and C(2,3);
- connect points A, B, C and T consecutively.
2 step: rectangle ABCT has length AB=4 units and width BC=3 units. Then
sq. un.
3 step:
sq. un.
sq. un.
sq. un.
4 step:
sq. un.
Answer: in step two you write dimensions of rectangle ABCT: length 4 units and width 3 units. Correct choice is B.
Answer:
2y-10
Step-by-step explanation:
-2(7-y)+4
distribute:
=(-2)(7)+(-2)(-y)+4
= -14+2y+4
Combine like terms:
= -14+2y+4
=(2y)+(-14+4)
= 2y+-10
