A Rectangle is a quadrilateral that has two sets of congruent sides.
(area of a rectangle, = base*height)
The fence (70m) consists of only 3 sides, two of which are congruent. Two factors of 600 equal the sum of the dimensions of the fence. Confused?
20 & 30 are factors of 600(area)
20+20+30=70(perimeter of fence only)
The garden, unlike the fence, includes the wall, which is equal to 30(the side that's missing it's congruent piece)
100=20+20+30+30, these are the dimensions of the garden.
Answer: All rational numbers are real numbers
Real numbers are those which can be represented on a real number line
Answer:
B
Step-by-step explanation:
The formula is (4/3) *pi*r^2, which means that it's 42^2 * pi * 4/3 = 7385.28
Answer:
b = a divided by 6
Step-by-step explanation:
Since a is equal to b times 6, you would have to divide a by 6 to find b
The sum s for n=8 is
.. s = (8 -2)(180°)
.. s = 1080°
Selection D is appropriate.

Put the number into the formula where the corresponding variable is, then do the arithmetic. A calculator can do the arithmetic for you, if necessary.
