Determine the total surface area of the following figure. a.114.54 square b.219.76 square centimeters c.229.08 square centimeters d.237.28 square centimeters >

We can make 2 calculations:

2 Blue Areas = 2 * 4 * 14.9 = 119.20 sq cm

2 Red Areas = 2 * 8.2 * 6.7 = 109.88 sq cm

Total = 229.08 sq cm

Answer is "C"

Step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
