Answer:

-32x² +8x -8
See below about the process

Step-by-step explanation:

The simplified expression is ...

3x(x -12x) +3x² -2(x -2)²

= 3x(-11x) +3x² -2(x² -4x +4) . . . . . simplify contents of parentheses

= -33x² +3x² -2x² +8x -8 . . . . . . . .eliminate parentheses

= (-33 +3 -2)x² +8x -8 . . . . . . . . . . group the coefficients of like terms

= -32x² +8x -8

Answer:

Options (1),(3),(4) are correct and Options (2) and (5) are incorrect.

Step-by-step explanation:

$3x(x-12x)+3x^{2}-2(x-2)^{2}$

$=3x(x-12x)+3x^{2}-2(x^{2}-4x+4)$ $=3x^{2}-36x^{2}+3x^{2}-2x^{2}+8x-8$ $=[tex]-32x^{2}+8x-8$

In this question we do the the simplification of term -2(x-2)^2 by squaring (x-2) then we find simplified product is not a binomial.

After multiplying, the like terms are combined by adding and subtracting.

The parentheses are eliminated through multiplication and then

The final simplified product is $-32x^{2}+8x-8$

Therefore Options (1),(3),(4) are correct and Options (2) and (5) are not correct.

For what values of x does the graph of f have a horizontal tangent? (Use n as your integer variable. Enter your answers as a com

BartSMP [9]

F(x) = x - 2sinx

To find for what values of x graph has tangents we need to differentiate function f(x).
f'(x) = 1-2cosx
Now, if we want to have horizontal tangents we need to make function f'(x) equal to 0 because at minimum or maximum of function f(x) tangent is horizontal.

1-2cosx = 0
cosx = 1/2
x = pi/3 + 2*n*pi and
x = -pi/3 + 2*n*pi

Explanation: cosx = 1/2 for both 60° and -60°. If we make one circle cosx will be equal to 1/2 for 420 and 300 degrees. Writing degrees in radians (using pi) we can write formulas above where 2*pi represents one full circle and n is an integer which represents how many circles we made.

Given the equation 4x + 7 = 3(2x − 5), solve for the variable. Explain each step and justify your process. B. Sam solved a simil

arlik [135]

Equation: 4x + 7 = 3(2x - 5)

Step-by-step solution:

• Expand brackets

-> 4x + 7 = 6x - 15

• Move x variable to a side and the numbers to another

-> 4x - 6x = -15 - 7

• Solve

-> -2x = -22

• Multiply both sides by (-1)

-> -(-2x) = -(-22)
-> 2x = 22

• Divide both sides by 2

-> x = 22/2

-> x = 11

• Justification
-> Put x = 11 in original equation
-> 4(11) + 7 = 3( 2(11) - 5)
-> 44 + 7 = 3(22 - 5)
-> 51 = 3(17)
-> 51 = 51
-> 51 - 51 = 0
-> 0 = 0
Since both sides are equal to each other, the answer to the equation is correct.

I don't know Sam's equation so I'm not gonna answer that.
