Order and Operate these please! I will give a lot of points. Please help asap (x +4) • 9

y + 7 + 8 – 7(x -8)

(4 – 5) + x(6 – 8)

y(4 – 8) – 3y

x + 8y – 16x(1- 3)

82 – x(4 – 8) + √25

53 – 4(y – 7y) - √81

x^2 – 4 – 5y - √36 • √144 + 23(x – 5x)

Step-by-step explanation:

a) (x +4)·9 = 9x +36

__

b) y +7 +8 -7(x -8) = y +7 +8 -7x +56 = y +15 -7x +56 = y -7x +71

__

c) (4 -5) +x(6 -8) = -1 +x(-2) = -2x -1

__

d) y(4 -8) -3y = y(-4) -3y = -4y -3y = -7y

__

e) x +8y -16x(1 -3) = x +8y -16x(-2) = x +8y +32x = 33x +8y

__

f) 8² -x(4 -8) +√25 = 64 -x(4 -8) +5 = 64 -x(-4) +5 = 64 +4x +5 = 4x +69

__

g) 5³ -4(y -7y) -√81 = 125 -4(y -7y) -9 = 125 -4(-6y) -9 = 125 +24y -9 = 24y +116

__

h) x² -4 -5y -√36·√144 +23(x -5x) = x² -4 -5y -6·12 +23(x -5x)

  = x² -4 -5y -6·12 +23(-4x) = x² -4 -5y -72 -92x = x² -92x -5y -76

y do u put "subscirbe to ence" on a app for ppl who need with their work?
