Find the value of X(2x + 4) (2x-9)
kotykmax [81]

2x +4)° 2x-9)°= 4x  2 +8x−9=3

 Pull out like factors :

  2x + 4  =   2 • (x + 2) (4 • (x + 2) • x) -  9

4x • (x + 2) -  9

Factoring  4x2+8x-9  

The first term is,  4x2  its coefficient is  4 .

The middle term is,  +8x  its coefficient is  8 .

The last term, "the constant", is  -9  

Step-1 : Multiply the coefficient of the first term by the constant   4 • -9 = -36  

Step-2 : Find two factors of  -36  whose sum equals the coefficient of the middle term, which is   8 .

     -36    +    1    =    -35  

     -18    +    2    =    -16  

     -12    +    3    =    -9  

     -9    +    4    =    -5  

     -6    +    6    =    0  

     -4    +    9    =    5  

     -3    +    12    =    9  

     -2    +    18    =    16  

     -1    +    36    =    35

x=3

Janet and her brother John went out to eat. Both paid the same amount. Janet got three burgers and left a $10 tip. John bought 4
lianna [129]

Answer:

Cost for 1 burger = 5 $

Amount spent by Janet  = 25$

Amount spent by John = 25$

Explanation:

Let the cost for burger be p.

Janet got three burgers and left a $10 tip

Amount spent by Janet  = 3 p + 10

John bought 4 burgers, but only left a $5 tip

Amount spent by John  = 4 p + 5

Both paid the same amount.

 So, we have  3 p + 10 = 4 p + 5

=> p = 5 $

So, cost for 1 burger = 5 $

Amount spent by Janet  = 3 x 5 + 10 = 25$

Amount spent by John  = 4 x 5  + 5 = 25$
