Answer:
Option A is correct.
Step-by-step explanation:
We have to eliminate x from the given system of equations by solving
-6x -4y=2
-4x-7y=2
We can do this by subtracting 3 times the second equation from 2 times the first equation we get
-12x -8y = 2
12x +21y =- 2
Sign of second equation changed because it is getting subtracted
Since, we got same quantity of x with opposite signs
Hence, it will get cancelled and so eliminated.
Therefore, Option A is correct.
Answer:
divide the figure into two parts.
area of square = side²
area of square =12²
area of square =144
area pf trapezium =1/2×(a+b)×h
area of trapezium =1/2×(12+6)×12
area of trapezium =108
area of polygon=144+108=252 unit²
To Solve this, you need to take 3 the number awarded for correct, and multiply that by 12 the number of correct. Which gets you 36. Then yoou need to find the difference between20 and 36 which gives 16. Then youu need to divide that by 2 to get your ansewr of 8 in 1. Follow the same procces for ii.
