okay since the first step is parenthesis, the next step would be exponents but you have none so you skip to multiplication, then you divide
divide is your answer

Step-by-step explanation:
Answer:
The correct option is 1.
Step-by-step explanation:
Given information: The coordinates of a right angled triangle ABC are A(0, 0), B(0, 4a – 5) and C(2a + 1, 2a + 6). Angle ABC = 90°.
It means AB and BC are legs of the right angled triangle ABC.
Side AB lies on the y-axis because the x-coordinate of both A and B is 0.
Two legs are perpendicular to each other. So, BC must be parallel to x-axis and the y-coordinate of both B and C is must be same.



Divide both sides by 2.

The value of a is 2. So the coordinates of triangle ABC are


The area of a triangle is

The area of triangle ABC is





The area of triangle ABC is 102. Therefore the correct option is 1.
2/3 a mile in half an hour
3 hours=6 x 2/3
6/1 x 2/3 = 12/3
12/3 =4 miles in 3 hours
