Answer:
Step-by-step explanation:
3 times 4 is 12. you can solve this by dividing 12 by 3, or by skip counting and using repeated addition.
AD is perpendicular to BC so slope Ad = -1/slope of BC
Slope of BC = (2 - (-1)) / (- 6- 3) = 3 / -9 = -1/3
So slope of AD = -1 / (-1/3) = -3/-1 = 3 Answer
-3(2x-4)+8x-8
-6x+12+8x-8
2x+4
x=2
Answer:
Its D because 2×2×2 equals 8 and they are both minus and knowing - times - makes + so it becomes 8
