Answer: 100

Hi!

ok so the Pythagorean theorem is

c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10

so the other side is 10.

the square 8 is 8*8

and square 6 is 6*6

so the other square is 10*10=100.

so the area of the blank square is 100.

Step-by-step explanation:

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive int
Goshia [24]

Answer:

a=1

b= -6

c=48

Step-by-step explanation:

x^2=6(x-8)

x^2=6x-48

x^2-6x+48

a,b are the coefficients of x^2 and x

c is the constant value present

Therefore it is basically written as ax^2+bx+c

and comparing with the answer x^2-6x+48,

a=1, b= -6, c=48

8_murik_8 [283]

Answer:

$179.76

Step-by-step explanation:

We can calculate the total cost as follows.  The 1.00 represents the before-tax cost of the dehumidifier and the 0.0575 the 5.75% sales tax:

Total cost of dehumidifier = (1.00+0.0575)($169.99) = $179.76 (to the nearest
