Answer:

14

Step-by-step explanation:

{3x}^{2}  - 2y \\ 3 { \times 3}^{2}  - 2 \times 5 \\ 27 - 10 = 17

{2x}^{2}  - 3y \\ 2 \times  {3}^{2}  - 3 \times 5 \\ 12 - 15 =  - 3

17 - 3 = 14

11 I’m pretty sure. Since 3x times 2 is 18 - 2y which is 10. The first thing is 10. And since 2x times two is 12, if you subtract that by 3y which is 15 you would get -3. The difference of 10 and -3 you get 13.

Subtract the average from the sales to get the deviation.

Aug. 1700 - 1412.50 = 287.50

Sept. 1125 - 1412.50 = -287.50

Oct. 1850 - 1412.50 = 437.50

Nov. 1500 - 1412.50 = 87.50

Dec. 1050 - 1412.50 = -362.50

What is the area of an isosceles trapezoid, if the lengths of its bases are 16 cm and 30 cm and the diagonals are perpendicular
kicyunya [14]

Call the point of intersection of the diagonals point X.

Each base is the hypotenuse of an isosceles right triangle whose sides are the diagonals and whose 90° angle is at X. The altitude of that triangle (⊥ distance to the base from X) is half the length of the hypotenuse. Then the height of the trapezoid is half the sum of the base lengths.

The area of the trapezoid is the product of the height and half the sum of the base lengths, hence is the square of half the sum of the base lengths.

... Area = ((16 cm +30 cm)/2)² = (23 cm)² = 529 cm²
