Answer:
A ≈ 78.6 ft²
Step-by-step explanation:
Height of an equilateral triangle of side 6
h = √(6² - 3²) = √27
A = 3(½(6)(7)) + (½(6)(√27))
A = 63 + 15.6
-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
12 and 13 are exempt because the opposite is -11 is 11, and all others above -11 and below 11 are the integers.
4
28 divided by 7=4
list the squares
1x1=1
2x2=4
3x3=9
4x4=16
16 the answer because 1+6=7

$400
If the price after taking 25% off is $300, then $300 is 75% of the original price.
$300 = 0.75p
$300/0.75 = p = $400
The original price was $400.

0.25 × $400 = $100
$400 -100 = $300 . . . . the price after taking 25% off
