Answer:

x= -2

Step-by-step explanation:

first add the four to the other side so then the equation looks like -4x=8

and then you divide the -4 by the 8 so the answer would be x=-2

VMariaS [17]

Answer: -2

Explanation: The coefficient is the number to the left of the variable.

Another example would be that 10xy has the coefficient 10.

Something like x^2 has coefficient 1 because x^2 = 1x^2.

Step-by-step explanation:

If you take 2, 8 and make it a ratio you get 2 : 8.

Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.

For the other answer, you want to divide 2 by 8.

(Hope this helps) :)

Which expression is equivalent to sec2x − 1?

aleksandr82 [10.1K]

Answer:

tan²x

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1

Divide all terms by cos²x

$\frac{sin^2x}{cos^2x}$ + $\frac{cos^2x}{cos^2x}$ = $\frac{1}{cos^2x}$ , that is

tan²x + 1 = sec²x ( subtract 1 from both sides )

tan²x = sec²x - 1

A box is shaped like an octagonal prism. Here is what the base of the prism looks like. If the height of the box is 7 inches, th

Monica [59]

Answer:

The volume of the box is 33.796 cubic inches

Step-by-step explanation:

Given

$Height = 7in$

See attachment for the base of the prism

Required

The volume of the box

From the attachment, we have:

$a = 1in$ -- side length of the octagon

The area is then calculated as:

$Area = 2 * (1 + \sqrt 2)a^2$

So, we have:

$Area = 2 * (1 + \sqrt 2)* 1^2$

$Area = 2 * (1 + \sqrt 2)* 1$

$Area = 2 * (1 + \sqrt 2)$

Evaluate the square root

$Area = 2 * (1 + 1.414)$

$Area = 2 * (2.414)$

$Area = 4.828$

The volume is then calculated as:

$Volume = Height * Base\ Area$

$Volume = 7 * 4.828$

$Volume = 33.796$
