Answer:

The side length is 11 inches

Step-by-step explanation:

The volume of a cube is given by

V = s^3 where s is the side length

1331 in ^3 = s^3

Take the cube root of each side

(1331 in ^3 ) ^1/3 = s^3 ^ 1/3

11 in = s

5(2k - 3 )-3(k+4)/ 3k+2; k= -2

svetoff [14.1K]

Answer:

First, we substitute k=-2 in the given expression and we calculate the numerical value.

$\frac{5(2k-3)-3(k+4}{3k+2} =\frac{512(-2)-3](-2+4}{3(-2)+2}$

$=\frac{5(-4-3)-3(2)}{-6+2}$

$=\frac{5(-7)-6}{-4}$

$=\frac{-41}{-4}$

$=\frac{41}{4}$

Please someone help me !! :(

Answer: 27 times bigger.

Step-by-step explanation:

You need to use the following formula to find the volume of a Square pyramid:

$V=\frac{1}{3}s^2h$

Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.

Knowing that:

$s_A=12\ in\\\\h_A=8\ in\\\\\\s_B=36\ in\\\\h_B=24\ in$

You can find the volume of the Pyramid A and the volume of the Pyramid B:

$V_A=\frac{1}{3}(12\ in)^2(8\ in)\\\\V_A=384\ in^3\\\\\\V_B=\frac{1}{3}(36\ in)^2(24\ in)\\\\V_B=10,368\ in^3$

Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.

You get:

$\frac{10,368\ in^3}{384\ in^3}=27$

Evaluate the expression when x=10, y=−2, and z=−5. −x2+6zy=

Burka [1]

x = 10

y = -2

z = -5

-x2 + 6zy = ???

Plug it in:

-(10)(2) + 6(-5)(-2) = ???

-10 x 2 + 6 x 10= ???

-20 + 60 = 40

Therefore, plugging the values in would make it equal 40.
