Answer:
There's no choices in your question but perpendicular lines cross through each other and intersect.
Step-by-step explanation:
Answer:
1000 m of fence can make a 3-sided enclosure of 125,000 m²
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the perpendicular dimension is ...
width = (1000 -x)/2
and the enclosed area is ...
area = length×width = (x)(1000 -x)/2
This describes a downward-opening parabola with zeros at x=0 and x=1000. The vertex (maximum) is halfway between, at x=500.
Then the maximum area is ...
area = (500)(1000 -500)/2 = 125,000 . . . . square meters
From information given I can only tell you that
a=1/2bh
multiply both sides of = by 2 and you'll cancel the 1/2 out on the right side making
2a=bh
then divide both sides by b, canceling out the b on the right side giving you
2a/b=h
so h=2a/b
I think the pattern is that you multiply the first number by the second , then add the first number. SO:
e.g. for the first one 1 x 4 = 4 , 4 + 1 = 5
for the second one 2 x 5 = 10, 10 + 2 = 12...
So for 8+11:
you do 8 x 11 = 88 , 88 + 8 = 96
