Have you used PEMDAS if not the abbreviation stands for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. So you start with 3² = 3x3 = 9 now 5x6=30 so now you have a equation of (4 + 7 x 9 - 30) = 4 + 63 - 30 = 67 - 30 = 37 I hope I helped!!!!

What is the value of x?

inn [45]

Answer:

x = 19

Step-by-step explanation:

These type of angles always equal each other

3x - 3 = 6x - 60

Subtract 3x from both sides

-3 = 3x - 60

Add 60 to both sides

57 = 3x

19 = x OR x = 19

After the expression (x^8)^3/4 is simplified as much as possible, x is raised to what exponent?

KonstantinChe [14]

Answer:

x^6

Step-by-step explanation:

Given (x^8)^3/4

To find : simplified as much as possible, x is raised to what exponent.

Solution : We have given that (x^8)^3/4

By the exponential rule : x^a(b) = x^ab

Then we have

=x^(8/4 *3)

=x^(2 *3)

=x^6

Do line segments with the given lengths form a right triangle? State whether the line segments with the given lengths form a rig

Dvinal [7]

Given:

19, 180, 181

To be able to determine if the given lengths form a right triangle, the following condition must be met:

$\text{ a}^2\text{ + }b^2=c^2$

Let's check.

a.) At a = 19, b = 180, c = 181

$\begin{gathered} \text{ a}^2\text{ + }b^2=c^2 \\ (19)^2+(180)^2=(181)^2 \\ 361\text{ + 32,400 = 32,761} \\ 32,761\text{ = 32,761} \end{gathered}$

Therefore, the given lengths could form a right triangle at a = 19, b = 180 and c = 181.

The answer is yes.

It just happened to be that we got the right answer on the first try, you must also examine at a = 180, b = 181, c = 19 and a = 181, b = 19, c = 180 if the first try didn't meet the right condition.

If you failed to get, then the given lengths could not form a right triangle. The answer would be no.
