Hi I really need help with this question please,

Mrrafil [7]

Answer:

${ ( \sqrt{30 - x} )}^{2} = {x}^{2} \\ 30 - x = {x}^{2} \\ \\ {x}^{2} + x - 30 = 0 \\ delta = 1 - 4 \times ( - 30) \times 1 = 121 \\ x1 = \frac{ - 1 + \sqrt{121} }{2 \times 1} = \frac{ - 1 + 11}{2} = 5 \\ x2 = \frac{ - 1 - \sqrt{121} }{2 \times 1} = \frac{ - 1 - 11}{2} = - 6 \\$

Francine applies the commutative property to the product. (−8/9)⋅(−13)⋅(18) Which expression illustrates the commutative propert

oksian1 [2.3K]

The commutative property implies that, the order of multiplication is not important.

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

Commutative property of multiplication states that:

If $a \times b = b \times a$

The expression is given as:

$(-\frac 89)\cdot (-13) \cdot (18)$

To get the commutative expression, we simply change the position of each factor in the expression.

So, some possible equivalent expressions are:

$(18) \cdot (-13) \cdot (-\frac 89)$

$(18)\cdot (-\frac 89) \cdot (-13)$

$(-13) \cdot (18) \cdot (-\frac 89)$

There are several other equivalent expressions.

From the list of options;

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

Find the volume of a pyramid with a square base, where the perimeter of the base is

Kobotan [32]

Answer:

6.8 cubic feet

Step-by-step explanation:

7.3/4=1.825, which is the side length, 1.825*1.825=20.2575 and then ypu divide 20.2575 by 3 because it is a pyramid and that gives you 6.7525

What is the volume of a cylinder with a base radius of 2 and height of 6 ?

vodomira [7]

Answer:

V = 24pi

or 75.36 ( using 3.14 for pi)

or 75.39822369 ( using the pi button)

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the radius and the height

V = pi (2)^2 * 6

V = pi 4*6

V = 24 pi

If we approximate pi by 3.14

V = 3.14 * 24 = 75.36

If we use the pi button

V =75.39822369
