Answer:

4 + 7x – 2

Step-by-step explanation:

Equivalent Expressions

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

$2x + 2+ 2x + 3x -8=7x-6$

Now for the second expression

$4 + 7x -2=7x+2$

The third expression simplifies to

$-2 + 5x + 2x - 4=7x-6$

Finally, this is the simplification for the expression

$8x - x - 6=7x-6$

As seen, the only expression not equivalent to the other three is 4 + 7x – 2

A rectangular sign has length of 3 and 1/2 ft and a width of 1 and 1/8 ft. Will the area of the sign be greater or less than 3 a

zavuch27 [327]

Answer:

$Area = 3\dfrac{15}{16}\ sq\ ft$

Area is greater than $3\frac{1}{2}$ sq ft.

Step-by-step explanation:

Length of rectangular sign board = $3\frac{1}{2}$ ft

Width of rectangular sign board = $1\frac{1}{8}$ ft

Area of a rectangle is given by the formula:

$A = Length \times Width$

To find the area, we are going to multiply $3\frac{1}{2}$ with $1\frac{1}{8}$ .

$1\frac{1}{8}$ is greater than 1.

Therefore the multiplication will be greater than $3\frac{1}{2}$ .

Hence, we can say that area will be greater than $3\frac{1}{2}$ sq ft.

Area of the sign:

$A = 3\dfrac{1}{2}\times 1\dfrac{1}8\\\Rightarrow A = \dfrac{7}{2}\times \frac{9}8\\\Rightarrow A = \dfrac{63}{16}\\\Rightarrow A = 3\dfrac{15}{16}\ sq\ ft$

faltersainse [42]

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we know that

Discrete data are those data which is countable and it is expressed in exact numerical form.

Continuous data are those data which is lie within the interval and it varies so it does not expressed in exact numerical form.

Here, the number of iphones sold today at an Apple store is countable and it can be expressed in exact numbers.

So, it is considered as discrete.

Hence, Option 'e' is correct.
