Answer:
(B) 18.
Step-by-step explanation:
We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).
First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.
We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.



Therefore, the perimeter of the given quadrilateral is 18 units.
The circumference is the measurement around the circle.
Answer: 30 i believe
Step-by-step explanation:
The answer is the last option: The associative property of multiplication
The answer to this question would be: 5 second
In this question, you are given the initial distance (300ft), car velocity(48ft/s) and the final distance(60ft). You are also given the equation to calculating the distance, so this question should be easier. The question is when the time where the distance is 60 ft. So the answer would be:
distance= 300-48t
60 = 300ft- 48t
48t= 300- 60=240
t= 5
