You can simply put the equation as 9x = 36 and divide by 9, then x = 4

Answer:

Step-by-step explanation:

the x-intercept is where y = 0 so you input 0 for y. It then becomes 9x = 36 so to find x its 39 divided by 9 which is 4 so the x intercept is 4

Richard cut his pizza into 12 slices. Gianni cut his pizza into 6 slices, and ate 2 slices. Together, ate 9/12 of one pizza. How

andrew11 [14]

FInd the common denominator: 12

That means gianni ate 4/12 of his pizza

Subtract 9/12 by 4/12

You get 5/12

That means 5/12 must be your answer

Richard ate 5/12 of his pizza

Luis has a pyramid shaped plant pot. It has a square base with a side length of 36\text{ cm}36 cm36, start text, space, c, m, en

Answer:

$15,552cm^3$

Step-by-step explanation:

Given

Side of length of the square base = 36cm

Height of the pyramid shaped plant pot = 36cm

Since the question does not specify what to look for, we can as well look for the volume of the pyramid shaped plant pot.

Volume of a pyramid = $\frac{Base\ area * Height}{3}$

Since the base is square

Base area = L²

Base area = 36²

Base area = 1296cm²

Height of the pyramid = 36cm

Substituting the resulting values into the formula

$Volume = \frac{1296*36}{3}\\ \\volume = 1296*12\\\\Volume \ of \ the \ pyramid = 15,552cm^3$

Find all zeros of <br>f(x)= x^3 + 3x^2 − 3x − 1

PSYCHO15rus [73]

F(1) = 1^3 + 3(1)^1 - 3 - 1 = 1 + 3 - 3 - 1 = 0

so one zero is x = 1, and x-1 is a factor

dividing f(x) by x - 1 gives x^2 + 4x + 1

x = [-4 +/- sqrt (16 - 4)] / 2

x = -0.27, -3.73

zeroes are 1 , -0.27 and -3.73 Answer
