Answer:

A =  5 {x}^{2}  + 6x + 1

Step-by-step explanation:

A =  \frac{(a + b)h}{2}  = \frac{(6x - 5 + 4x + 7)(x + 1)}{2}  =  \frac{(10x + 2)(x + 1)}{2}  =  \frac{2(5x + 1)(x + 1)}{2}  = 5 {x}^{2}  + 6x + 1

What is the algebraic expression for the following word phrase: the product 4 more than x and 6?
Dmitry [639]

Answer: b. 6(x + 4)


Step-by-step explanation:

The given word phrase = the product 4 more than x and 6

where , 4 more than x is equivalent to x+4

Therefore the algebraic expression for the given word phase "the product 4 more than x and 6"

=6\times(x+4)

\\=6(x+4)

Hence b. is the right option.

The algebraic expression for the given word phase is \\6(x+4)

Methanol is a Liquid form if its temperature is between - 93.9 C and 64.96 C At what temperatures will methanol be in liquid for
alexgriva [62]

Option A : 25° C

Option C : -43° C

Option E : 0° C

Explanation:

It is given that the Methanol is in liquid form if its temperature is between -93.9°C and 64.96°C.

Let x represents the Methanol's temperature. Writing the temperature in interval notation, we have,

-93.9

Now, let us determine from the given options that the temperatures at what are all the temperatures the methanol will be in liquid form.

Option A: 25° C

It is obvious that the 25° C lies in the interval -93.9

Hence, at 25° C Methanol will be in liquid form.

Thus, Option A is the correct answer.

Option B: -95° C

We can see that the temperature -95° C does not lie in the interval -93.9

Hence, at -95° C Methanol will not be in liquid form.

Thus, Option B is not the correct answer.

Option C: -43° C

We can see that the temperature -43° C lies in the interval -93.9

Hence, at -43° C Methanol will be in liquid form.

Thus, Option C is the correct answer.

Option D: 67° C

We can see that the temperature 67° C does not lie in the interval -93.9

Hence, at 67° C Methanol will not be in liquid form.

Thus, Option D is not the correct answer.

Option E: 0° C

We can see that the temperature 0° C lies in the interval -93.9

Hence, at 0° C Methanol will be in liquid form.

Thus, Option E is the correct answer.

Option F: 89° C

We can see that the temperature 89° C does not lie in the interval -93.9

Hence, at 89° C Methanol will not be in liquid form.

Thus, Option F is not the correct answer.
