Answer:
Yes it is. You can use the coodinates to find the distance of each side using the distance formula. After that, then you can proceed with 1/2bh.
Answer:
10 units
Step-by-step explanation: Using a coordinate plane, draw a right triangle so the legs are 6 and 8 units long, then use your formula A to the second power + B to the second power equals C to the second power.
Answer:
1) 16x -4
2) 7x + 45
Step-by-step explanation:
1 ) 6x + 2(5x -2)
we are going to open the bracket
we have,
6x + 10x - 4
16x -4
4(4x - 1).................................................... simplified
number 2
7x + 3(8+7)
7x +24 + 21
7x + 45........................................................... simplified
so therefore the solution to the first and 2nd question is
1) 16x -4
2) 7x + 45
Rewrite the first equation: 3y=-2x-17. The equations are coincidental and -17 is one sixth of -102 so the other coefficients need to be multiplied by 6: 18y=-12x-102.
