(3^3 - 9 )^2 ? how would i simplyify this expression

(3^3 - 9 )^2

First do what is inside the parenthesis:

3^3 = 27

Now you have:

(27-9)^2

Subtract:

27-9 = 18

Now you have:

(18)^2

Raise 18 to the second power:

18^2 = 324

The simplest result is 324.

Step-by-step explanation:

Note that 3^3 = 27.  Thus, 9 is a factor of both 3^3 and 9 inside those parentheses.

Then (3^3 - 9 )^2 is the same as [ 9(3-1) ]^2, or

[ 9(2) ]^2, or 81*4 = 324.

vwhat effect does the word head have on the meaning of this passage?

a. it demonstrates how intelligent he was.

b. it shows he was a favorite of the teachers.

c. it indicates he would be a good preacher.

d. it reveals how self-important he was.

how does the choice of the word head contribute to the passage’s tone?

a. it offers a sense of entitlement.

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
