Answer:
B
Step-by-step explanation:
Formula: 4*((15*7)/2) + 15^2
This is the area of the four triangles combined (210 cm^2) plus the area of the square (225 cm^2)
(-3+) /2, (3+) / 2 which is approx -3.791 and 0.791
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
20, 31, 33, 35, 55, 57, 58, 59, 72, 73, 79, 86, 87, 88
The data set is split by digit. So 2|0 becomes 20. 5|5 becomes 55. Using this method, the data set is
