D $321

Its b

Step-by-step explanation:

I used a calculator B)

B.-79

Step-by-step explanation:

Ok since Sarah deposited four 125.25 paychecks she has $501 dollars in her bank to spend this is because 125.25 x 4= 501 , then sarah makes four withdrawls each withdrawl is for 45 dollars 45 x 4= 180 then sarah withdraws 400 dollars so if you  add all her withdrawls together 400+180=580 so she has spent 580 dollars she had 501 in her account to spend so 580-501=79 this is wrong because she is negitive but taking the highest number and subtracting the smaller one is easier so she has -79 dollars in her account

b

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
