Basically that is a certain order where you can swap around the numbers. The answer is that the problem is correct because both equal 49x
4 because if you add 4 and 8 that would be 12
Answer:
A) convex and regular
Step-by-step explanation:
The polygon has all equal sides so it's regular ; 8 equal sides so it's a regular octagon.
An octagon has no angles pointing inwards so it's convex
Answer:
convex and regular
Answer:
Step-by-step explanation:
Let length be x and breadth be y .
Along the river no fencing is required so total boundary line of the rectangular land = x + y + y = x + 2y
add divider to it so total length
= x + 2y + y = x + 3y
x + 3y = 2400
area A = xy
y ( 2400 - 3y ) = A
2400y - 3y² = A
For maximum area dA / dy = 0
2400 - 6y = 0
y = 400 yards.
x = 1200 yards
largest area = xy
= 48000 sq yards.
Answer:
27.73 cm
1. Find the area of the rectangle: 8x7=56 cm
2. Find the area of the circle: pi x 3 squared= 28.2743338....cm
3. Subtract area of the circle from the area of the rectangle: 56 - 28.27433=27.72567cm
4. Round to the nearest hundredth: 27.73 cm
