Each choice has 7x and 3x which multiply to 21x^2.
The original trinomial has positive 20 and positive 43, so all factors of 21 and of 20 must be positive.
Only choice B has all positive terms, so choice B must be the answer.
Answer:
It's called a triangle.
Step-by-step explanation:
Answer:
The slope is 1/2
Step-by-step explanation:
To find the slope
m= (y2-y1)/(x2-x1)
= (8-2)/(5--7)
= (8-2)/(5+7)
= 6/12
= 1/2
Step-by-step explanation:
648/18
18/64=3 remaining 10
bring 8 down making 108
108/18=12
3 and 12=312
ans =312
