None of these are right

y=$350 because that is her total.

m=$25 because each game cost that.

B=$200 because that's how much the console cost.

$350=$25x+$200

The side length of the square base is 18 inches and the height of the pyramid is 9 inches.

Step-by-step explanation:

Step 1:

The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and \frac{1}{3}.

The volume of a square pyramid, V = a^{2} \frac{h}{3}.

Step 2:

From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.

The height of the pyramid is from the base to the top, h = \frac{x}{2} inches .

The volume of a square pyramid, V = 972.

Substituting the known values, we get

972 = (x)^{2} (\frac{x}{2})  (\frac{1}{3} ) = \frac{x^{3} }{6} .

x^{3} = 6(972) = 5,832. x = \sqrt[3]{5,832} = 18.

So x is 18 inches long.

The side length = x = 18 inches.

The height of the pyramid = \frac{x}{2} = \frac{18}{2} = 9 inches.

Can someone do this fast ? I need it for tomorrow
gregori [183]

Answer:

Step-by-step explanation:

hg(x) means you multiply h(x) times g(x) and then we will set it equal to 3x^2+x-1.

hg(x) = x^2(x+2) which simplifies to

x^3+2x^2. Now set that equal to 3x^2+x-1:

x^3+2x^2=3x^2+x-1 and get everything on the same side and factor:

x^3-x^2-x+1=0. Factor by grouping:

(x^3-x^2)-(x+1)=0 and factor out what's common in each set of ( ):

x^2(x-1)-1(x-1)=0 which factors out to

(x^2-1)(x-1)=0. But x^2-1 factors somoe to:

(x + 1)(x - 1)(x - 1) = 0 So the solutions for this are

x = -1, 1
