Which shows a reasonable estimation for 124% of 42 using the distributive property? A.(120 percent) (40) + (4 percent) (40) = (4,800) + (160) =4,960
B.(100 percent) (40) + (20 percent) (40) = (4000) + (800) = 4,800
C.(100 percent) (40) + (20 percent) (40) = (40) + (8) = 48
D.(100 percent) (40) + (20 percent) (40) = (40) + (80) = 120

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

the radius is multiplied by √6.

step-by-step explanation:

if a circle has a radius of 10.9 cm and the area is multiplied by 6, the radius is multiplied by √6.
