-5×=-50

Answers

Answer 1

Answer: so -5x=-50
multiply both sides by -1
5x=50
divide by 5
x=10
check
-5 times 10=-50
-50=-50

What is the perimeter of the triangle expressed as a polynomial? Length: 8x-2
Length: 5x-4
Width: 9x-3
If you could show me how you got the complete answer I would really appreciate it.

Answers

The perimeter is the sum of the lengths of the three sides of the triangle. If "width" is the length of the 3rd side, then the perimeter is
P = (8x-2) + (5x-4) + (9x-3)
P = 8x + 5x + 9x -2 -4 -3
P = (8+5+9)x -(2+4+3)
P = 22x - 9

Determine whether the following problem involves a permutation or combination. (It is not necessary to solve the problem.) How many different 33-letter passwords can be formed from the letters Upper QQ, Upper RR, Upper SS, Upper TT, Upper UU, Upper VV, and Upper WW if no repetition of letters is allowed?

Answers

Answer:

Permutation

Step-by-step explanation:

Since we are talking about passwords the order of the letters matters, i.e, the pasword UpT is different to the pasword pUT. Therefore, the problem involves all the permutations of 33 letters, from the given letters, where no repetitions of letters are allowed.

What is a simpler form of the radical expression? sqrt 36g^6 A. 36|g^3| B. 36g^4 C. 6|g^3| D. 6g^4

Answers

Answer:

Lesson 1 Unit 2: Roots and Radical Expressions

1 = a (no real root)

2 = c (-0.05)

3 = c (6lg^3l)

4 = d (5x^7y^8)

5 = a (3x^2/5y)

5/5 100%

Step-by-step explanation:

First we write down this expression:
$\sqrt{36* g^(6) }$
We notice that 36 is a square of 6 so we write:
$\sqrt{ 6^(2)*g^6 }$

Now, square root we imply on each of factors (g^6 and 6 ^2)
we get.
6*|g^3|
The reason for absolute value is because of variable g.
