Answer 1

Explicación paso a paso:

3y^3; y = 3

3(3)^3 = 3(27) = 81

4 + u + 10; u = 5

4 + 5 + 10 = 19.

3 - u - u; u = 1

3 - 1 - 1 = 3.

6b/b; b = 10

6(10)/10 = 60/10 = 6.

(b - 4)/b; b = 7

(7 -4)/7 = 3/7.

(c + 3).c; C = 7

(7 + 3).7 = (10).7 = 70.

5X + 12; X = 2,5

5(2,5) + 12 = 12,5 + 12 = 24,5.

28 - 2m; m = 7

28 - 2(7) = 28 - 14 = 14.

-3a + 1; a = 2

-3(2) + 1 = -6 + 1 = -5.

X^2 + 8X - 10; X = 2

(2)^2 + 8(2) - 10 = 4 + 16 - 10 = 10

X^2 + 8X - 10; X = -3

(-3)^2 + 8(-3) - 10 = 9 - 24 - 10 = -25.

5y^3 - 2y + 9; y = 3

5(3)^3 - 2(3) + 9 = 5(27) - 6 + 9 = 135 - 6 + 9 = 138

5y^3 - 2y + 9; y = -2

5(-2)^3 - 2(-2) + 9 = 5(-8) + 4 + 9 = -40 + 4 + 9 = -27

5a^2 + 2bc + 3d; a = 2; b = -1; C = 3

5(2)^2 + 2(-1)(3) + 3d = 5(4) - 6 + 3d = 20 - 6 + 3d = 14 + 3d.

-5ab + 1; a = 2; b = -1

-5(2)(-1) + 1 = 10 + 1 = 11
