Can someone with this? idk how to do it

a =12sqrt(2)

Step-by-step explanation:

The Pyhtagorean theorem is a^2 +b^2 =c^2

where a and b are the legs of the triangle and c is the hypotenuse

We know one of the legs is 6 and the hypotenuse is 18.

a^2 + 6^2 = 18^2

a^2 +36 =324

Subtracting 36 from each side

a^2 +36-36 = 324-36

a^2 =288

Taking the square root of each side

sqrt(a^2) = sqrt(288)

a =sqrt(288)

Knowing sqrt(ab) = sqrt(a) sqrt(b)

a = sqrt(144)sqrt(2)

a =12sqrt(2)

step-by-step explanation:

$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
