Answer: Hi!
Remember, when you're subtracting a negative, that's equal to adding a positive. So -2-(-17) is actually equal to -2 + 17!
-2 + 17 = 15
The expression -2-(-17) is equal to 15.
Hope this helps!
Assuming the rectangles made will be of the same size:
Perimeter = 2(l + b)
For two rectangles,
Perimeter = 2 x 2(l + b)
240 = 4(l + b)
l + b = 60
l = 60 - b
Area = l x b
Area = 60b - b²
dA/db = 60 - 2b
Putting dA/db = 0
b = 30
Length = 60 - 30 = 30
Greatest available area of one triangle = 30 x 30
= 900 sq yd
Greatest total area that can be enclosed in both triangels
= 900 x 2
= 1800 sq yd
In this question, we're trying to find how many miles Sophie can drive in an hour.
We know that she drove 162 miles in 3 hours.
With the information above, we can find our answer.
We need to see how much she drives in 1 hour, so you would divide 162 by 3.
162 ÷ 3 = 54
This means that she drives 54 mph.
Answer:
54 mph
