We can find the volume of one of the cubes, then multiply by 3996 to find the total volume.

The edge lengths are 1/3, so the area of one cube is:

(1/3)^3 = 1/27

The area of the prism is:

3996 * (1/27) = 148 in^3

Solve for x 0°&lt;x&lt;360<br>3cos2x +sinx=1​
BartSMP [9]

Step-by-step explanation:

3cos2x +sinx=1

3(1-2sin²x)+sinx=1

3-6sin²x+sinx=1

sinx(-6sinx+1)=1

either

sinx=1

sinx=sin(90)

:.x=90

or

-6sinx+1=1

-6sinx=1-1

sinx=0/-6

sinx=sin0,sin180

:.x=0,180and90

Andrei has a job in the circus walking on stilts. Andrei is 11/10 meters tall. The foot supports of his stilts are 23/10 meters
vovangra [49]
First, add. 11/10 + 23/10 = 34/10
You can then simplify by finding the greatest common factor (2)
34/2, 10/2 = 17/5, or 3 and 2/5 
Andrei is 3 and 2/5 meters tall

-3² = -1*3² = -1 * 9 = -9 (order of operations) while (-3)² = (-3)(-3) = +9 or 9
mixas84 [53]

Answer:   20

Step-by-step explanation:

Assuming your question is:

Z² - X² - XY     X = -2, Y = 3, Z = -4

Substitute values

(-4)² - (-2)² - {(-2)(3)}

{(-4)(-4)} - {(-2)(-2)} - (-6)

(16) - (4) + 6

16 - 4 + 6
