X-2 = 6
6-2 - 4
x = 4
4^3= 64
64-1 = 63
The value of x^3 - 1 is 63

Hope I helped!

Multiply: (5x2y – 3xy2)(3xy2 + 5x2y)<br> Please help I need to get this one right!

Aliun [14]

Answer:

(1): "*-5x2y" was replaced by "*(-5x2y)".

(2): "x2" was replaced by "x^2". 1 more similar replacement(s).

STEP

Equation at the end of step 1

(3x • (y2)) • (0 - (5x2 • y))

STEP

Equation at the end of step

3xy2 • -5x2y

STEP

Multiplying exponential expressions :

3.1 x1 multiplied by x2 = x(1 + 2) = x3

Multiplying exponential expressions :

3.2 y2 multiplied by y1 = y(2 + 1) = y3

I believe the answer is ( -3•5x3y3)

The quadrilateral shown is a rectangle. What is the measure of CE?

aalyn [17]

Answer:

|CE|=2

Step-by-step explanation:

The quadrilateral is shown in the attachment

Recall that the diagonals of a rectangle are congruent.

This implies that:

|AC|=|BD|

We substitute the expressions to get:

$2x-6=5x-21$

This is now a linear equation in one variable.

Group similar terms to get:

$-6+21=5x-2x$

Simplify to get:

15=3x

Divide both sides by 3 to get:

$5=x$

Recall again that the diagonals of a quadrilateral bisect each other.

$|CE|=\frac{1}{2}|AC|$

$|CE|=\frac{1}{2}|2x-6|$

Plug x=5

$|CE|=\frac{1}{2}|2*5-6| =10-6=\frac{1}{2}*4=2$
