Answer:

1440

Step-by-step explanation:

3(x+4)(x+1)(x+2)(x-2)

Let x= 4

3(4+4)(4+1)(4+2)(4-2)

Evaluate each parentheses

3 ( 8) (5)( 6) (2)

Multiply

1440

If you meant

3(x+4)(x+1) = 3(4+4)(4+1) = 3 * 8 *5 = 120

(x+2)(x-2)=(4+2)(4-2)  = 6 *2= 12

Which expression is equivalent to the expression shown below?
posledela
The correct answer is:  [D]: " (-5 \frac{1}{4})x − \frac{1}{2}" .
_________________________________________________________

Explanation:

_________________________________________________________

 " -1/2(-3/2x + 6x + 1) −<span> 3x " ;

=  (-1/2 * -3/2 x) + (-1/2 * 6x) + (-1/2 * 1) </span>− <span>3x ; 


=   [ (-1 *-3) /(2*2)] x + (-3x) + (-1/2) ] </span>− <span>3x ; 

=   [ (3/4)x </span>− 3x − (1/2) ] −<span> 3x ; 

=   </span>(3/4)x − 3x − (1/2) − 3x ; 

= ?? ;   →  Combine the "like terms" ; 

           → "(3/4)x − 3x − 3x " =   ?? ;

                         → "(3/4)x − 3x = "(-9/4)x";

                         → "(-9/4)x − 3x = "(-21/4)x "  =  " (-5 \frac{1}{4})x " ;  

 →  The answer is:  " (-5 \frac{1}{4})x − \frac{1}{2} " ;

Find the indicated missing angle. Round to the nearest angle.
sladkih [1.3K]

Answer:

The missing angle 'x' is 22.29°.

i.e.     x\:=\:22.29^{\circ \:\:}

Step-by-step explanation:

Let 'x' be the missing angle of the triangle.

Using the formula

                     tan x = opp ÷ adjacent

                     tan x = 30 ÷ 72

                     tan x = 0.41

                          x=\tan ^{-1}\left(0.41\right)

                             x\:=\:22.29^{\circ \:\:}

Therefore, the missing angle 'x' is 22.29°.

i.e.     x\:=\:22.29^{\circ \:\:}
