5.last year, terry earned $19,436. this year, terry got a raise that increased her income to $23,457. a. how much more money did terry make this year? b. if terry gets the same raise again next year, what will her total income be then?

23,457 - 19,436 = 4,021

23,457 + 4,021 = 27,478

total income next year - 27,478

a)Terry made $4021  more this year .

b) If Terry gets the same raise again next year, her total income will be $27478.

Step-by-step explanation:

Terry initial income = $19436

Terry's new income = $23457

Increase in income = New income - initial income

                                =$23457-$19436

                                =$4021

a)So, Terry made $4021  more this year

Now we are given that If Terry gets the same raise again next year, what will her total income be then.

His income this year = $23457

Increase in income = $4021

So, Income in next year =$23457+ $4021=$27478

b) If Terry gets the same raise again next year, her total income will be $27478

i'm sorry i don't know

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
