P of <span>Regular heptagon = 7a = 7 x 12 = 84
Area </span>of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (84)(8)
Area of Regular heptagon = = 336
answer
B. 336
7)
P of Regular nonagon= 9a = 9 x 9 = 81
Area of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (81)(16)
Area of Regular heptagon = = 648
answer
D. 648
The slope of the given two points (-3, -2) and (-4, -4) is 2.
<h3>
What do we mean by slopes?</h3>
A line's slope, sometimes referred to as its gradient in math is a numerical representation of the line's steepness and direction.
How steeply a line slopes from LEFT to RIGHT is known as its slope.
By splitting a line's rise, or vertical change, by run, or horizontally change, one can calculate a line's slope.
The slope of a line is consistent no difference what two points on the line you choose (it never varies).
So, the slope of the given two points (-3, -2) and (-4, -4) is:
Slope formula: m = y2-y1/x2-x1
Now, put the values and evaluate the slope as follows:
m = y2-y1/x2-x1
m = -4-(-2)/-4-(-3)
m = -2/-1
m = 2
Therefore, the slope of the given two points (-3, -2) and (-4, -4) is 2.

Answer:
134
Step-by-step explanation:
They sold 134 hamburgers. The shop sold 268 cheeseburgers. 268 is 2x as much as 134. Divide 402 by 3, and you can find the amount of hamburgers. Times it by 2, and you find the amount of cheeseburgers.
Answer:
Total cost: 486.080$
Step-by-step explanation:
Original Price: 560.000$
Sale: 20%
Discount: 560.000$ * 20% = 112.000$
Discounted Price: 560.000$ - 112.000$ = 448.000$
Tax Rate: 8.5%
Tax: 448.000$ * 8.5% = 38.080$
Tax after Tax: 448.000$ + 38.080$ = 486.080$
