What does simplify the expression mean in algebra?

2 answers:

5 0

Reduce the number of terms in the expression by operating on like terms
for example
Simplify
x^2 - 3x + 4 + x^2 + 6x - 6

the like terms are the x^2 and x^2 , -3x and 6x and 4 and -6

so we have
x^2 + x^2 - 3x + 6x + 4 - 6
= 2x^2 + 3x - 2

This is the simplified form of the original expression

Simplifying the expression means In its simplest form
Here is a worked example
{[(3×8)÷12]+ 13}
{[24÷12]+13}
{2+13}
15÷3
=5
Remember
PEMDAS
Parenthesis first
Exponents
Multiplication and division what ever comes first
Addition and subtraction what ever comes first
some people remember this by
Please excuse my dear aunt sally
Goodluck!

Answer-180cm3

Explanation-

The volume of a prism is base x height so v=bh

Here the base equals 4cm times 15m which gives 60cm.And then the height is 3cm.So the total is 15cmx4cmx3cm=180cm³

5/4 (x - 5)= -6 what is x?

seropon [69]

So, you want to do the operations on both sides.
5/4 (x-5)=-6 becomes
x-5= -6/(5/4)
becomes
x= -6/(5/4)+5

and x=0.2
Hope this helped!

Which graph represents the linear function below? y-4= (4/3)(x-2)

svp [43]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y-4=(4/3)(x-2)$

This is the equation of a line into point slope form

The point is (2.4)

The slope is m=4/3

To plot the line find the intercepts

The y-intercept is the value of y when the value of x is equal to zero

For x=0

y-4=(4/3)(0-2)

y=(-8/3)+4

y=4/3

The x-intercept is the value of x when the value of y is equal to zero

0-4=(4/3)(x-2)

-4=(4/3)x-(8/3)

Multiply by 3 both sides

-12=4x-8

4x=8-12

x=-1

we have the points

(2,4), (0,4/3),(-1,0)

Plot the line

Note With only two points it was necessary to draw the line. The third point was calculated for didactic purposes.

see the attached figure
