Which of the following algebraic expressions is not simplified?

Hunter-Best [27]

Answer:

B. $x+2x$

Step-by-step explanation:

we will verify each options

option-A:

we have

$x+1$

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

$x+2x$

we can see that 2x and x are same type of terms

so, they are like terms

so, we can combine or simplify it

$x+2x=3x$

So, this expression is not in simplest form

this is TRUE

option-C:

we have

$x^2+x$

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

$5x^3-x$

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

The area of a parallelogram is the base times the height.

Area and base is given so we can use that to solve for the height:
72 = 6* h

h = 72/6
h = 12

The height is 12 units.

A rectangle has a perimeter of 103.6 inches and a base of 39 inches. What is the height?

rusak2 [61]

Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the total length we can find the total width.

See as follows,

103.6 - 78= 25.6

2 widths= 25.6

1 width= 25.6÷2

=12.8 In
