It would be D. Since X=2 in the beginning, and and is 8 in the end. 2*4 is 8. 
So, -5 times four would be 20, but not in this context. it would be -20.

Solve by factoring 6x^3 - 16x^2 - 32x = 0. Enter your work
Rashid [163]

Hey there! :)

Answer:

x = -4/3, 0, 4.

Step-by-step explanation:

Starting with:

6x³ - 16x² - 32x = 0

Factor out the greatest common factor between each term, or 2x:

2x(3x² - 8x - 16) = 0

Factor the expression inside the parenthesis:

2x(3x +4)(x - 4) = 0

Use the Zero Product Property to solve the equation:

2x = 0

x = 0

---------

3x + 4 = 0

3x = -4

x = -4/3

-------------

x - 4 = 0

x = 4

-------------

Therefore, the solutions to this equation are:

x = -4/3, 0, 4.

Plz help me with b,a , and b

2A) C is correct.

2B) If x + 13 = 28, solve.
x+13=28\\
x=15
If x = 15 and x + 13 = 28, you can solve it two ways:
1. Plug x into 4x + 26 to get a perimeter of 86, or
2. Redo the equation:
P=2(15)+2(28)\\
P = 30+56\\
P=86

3a. Since the 6z is negative, you want an expression the has 5z - (11z). Answers A and D have that in their answer.
But since the 13 is positive, you want the answer that subtracts the smaller number from the larger. Thus, D is your answer since it subtracts 2 from 15.

3b) You think about this question the same way; 6z is positive, so the smaller number is being subtracted from the larger, meaning that 11z - 5z is what you look for. C and D are the two that have that, so now let's look at the second term.
The 13 is negative, so you want the answer that has 2 - 15. The answer that has that is D.

Hope this helps :D

tensa zangetsu [6.8K]

Answer:

65 cm

Step-by-step explanation:

See the attached image.  The Pythagorean Theorem says in a right triangle, (leg)^2 + (leg)^2 = (hypotenuse)^2.

16^2+63^2=x^2\\256+3969=x^2\\4225=x^2\\x=\sqrt4225}\\x=65

F(x)=2x+3 find x=9 explain how you got the answer please help me I need the answer today
hram777 [196]
You would fill in 9 for x so your equation would be 2(9)+3 and you would then get 21. Therefore the answer is f(x)=21
