Question

-4(5а+3б)+5(4а-2р),якщо б= --8,р=-1,5, а= -1,2

Answer 1

Б = -8, p = -1,5, a = -1.2
-4(5*(-1,2)+3*(-8))+5(4*(-1.2)-2*(-1.5)) = -4(-6-24)+5(-4.8+3) = 120-9 = 111

Answer 2

To evaluate the expression -4(5a+3b)+5(4a-2p) when b = -8, r = -1.5, and a = -1.2, we substitute the given values of b, r, and a into the expression and simplify:

-4(5a+3b)+5(4a-2p) = -4(5(-1.2)+3(-8))+5(4(-1.2)-2(-1.5)) = -4(-6+24)+5(-4.8+3) = -4(18)+5(-1.8) = -72-9 = -81

Therefore, when b = -8, r = -1.5, and a = -1.2, the value of the expression -4(5a+3b)+5(4a-2p) is -81.
