Answer:
-7a^2 b^3
Step-by-step explanation:
-7(- a^2 )( -b^3 )
-7 * -a^2
A negative times a negative is a positive
7a^2
7a^2 * -b^3
A positive times a negative is a negative
-7a^2 b^3
Answer:
=8
Step-by-step explanation:
2(9)-(2)=8
18-2=8
16=8
=8
Simple multiplication so 3 x 24 = 72 so there are 72 boxes all together.
Answer:
A.Swing two arcs above and below the radius.
Step-by-step explanation:
The statement in option A is not used in constructing an inscribed hexagon. While constructing a inscribed hexagon, swinging of the arcs is done on only one direction to cut the circumference of the circle.
Steps of constructing an inscribed hexagon are :
1. Draw a circle on a paper with the help of a compass.
2. Mark a point on the circumference of the circle and make it a starting point.
3. Now with the same span on the compass, place the compass pointer on the previous point on the circumference and swing a small arc cutting the circumference.
4. Now with same span, place the compass pointer on the intersecting point of the small arc and the circumference and make second small arc on the circumference.
5. Continue making arcs on the circumference until we reach the 1st point.
6. Now join the intersecting points on the circle and make a hexagon.
So it i clear from the above that swinging two arcs below and above the radius is not required. Thus option A is not required.
Answer: 8/x - 5
Step-by-step explanation:
You find the quotient then you subtract, because the other way around doesn't work
