The lid is 15 by 30 so the area is 15*30 = 450 square inches

The front panel and back panel are both 30*24 = 720 square inches. The left and right panels are 24*15 = 360 square inches

Add up the front, back, left and right panel areas and we get: 720+720+360+360 = 2160

The total gray area is 2160 square inches compared to the white lid which is 450 square inches. Subtract these two values: 2160-450 = 1710

Answer: Choice B) 1710 square inches

kupik [55]

Answer:

y > 6 or y < -3

Step-by-step explanation:

y² - 3y > 18

Complete the square.

y² - 3y + 9/4 > 18 + 9/4

y² - 3y + 9/4 > 81/4

(y - 3/2)² > 81/4

y - 3/2 > 9/2, or y - 3/2 < -9/2

y > 6 or y < -3

X^2 - 9x -10 =0 has a discriminant of: a. 121 b. 72 c. -359 d. 41 e. 136

Feliz [49]

In the standard form of quadratic
$ax^{2} +bx+c$
the discriminant is
$b^{2} -4ac$
In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.
