Evaluate t - u/v when t=2, u= -8 and v = -1/2 simplify -2x-5y- 6x+4y simplify -5a-3b+8a-b simplify 7x^3+ 4y^2-9x^3-3y^2 simplify 16x^4-19x^4-8y^3-7x^4 simplify (-4x^2+3y-8)+(-5y-2x^2+1) simplify (-3a^3+ 7b +9b^2) simplify (5-p^2--q-3p^2) simplify -3(4h^5-k^4)=(5k^5+2k^4) simplify -(9w^3-2z+3)+4(3w^3-z) simplify -6(w^3-3z+4)-2(7z-5w^3)

Hi There!

-2x-5y- 6x+4y (−8x − y)

-5a-3b+8a-b (3a − 4b)

7x^3+ 4y^2-9x^3-3y^2 (−2x^3 + y^2)

16x^4-19x^4-8y^3-7x^4 (−10x^4 − 8y^3)

(-4x^2+3y-8)+(-5y-2x^2+1) (−6x^2 − 2y − 7)

(-3a^3+ 7b ^2)-(-6a^3+9b^2) (3a^3 − 2b^2)

(5-p^2-4q)-(-2-q-3p^2) (2p^2 − 3q + 7)

-3(4h^5-k^4)=(5k^5+2k^4) (Can't Simplify)

-(9w^3-2z+3)+4(3w^3-z) (3w^3 − 2z − 3)

-6(w^3-3z+4)-2(7z-5w^3) (4w^3 + 4z − 24)

Hope This Helps :)
