I need help please somebody answer ASAP please I’d highly appreciate it

2.(b) w= 3

3. x= -3 or x= 3

Step-by-step explanation:

2.(b) Method 1:

Simplify:

×5 on both sides:

Expand:

Bring constants to 1 side, w terms to the other:

Simplify:

Divide both sides by 3:

Method 2:

Multiply by 5 throughout:

Expand:

Simplify:

+9 on both sides:

-4w on both sides:

Simplify:

Divide by 3 on both sides:

3.

Multiply by 3x on both sides:

Expand:

Simplify:

Divide by 6 on both sides:

-9 on both sides:

Factorise:

*Since a²-b²= (a +b)(a -b),

Thus,

x +3= 0 or x -3= 0

x= -3 or x= 3

w = 3

Step-by-step explanation:

(6x-12)/3 + 4 = 18/x

Simplify fraction

2x -4 +4 = 18/x

Combine -4+4=0 Divide by 2 to reduce

x = 9/x

Multiply both sides by x

x² = 9

x = 3, -3

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
