Question

1). 5 (a-b). при a=-4, b=-2; 2). (-3)(a+x) при a=8, x=-10;

Answer 1

1). 5 (a-b). при a=-4, b=-2; 5(-4+2)=-20+10=-10;//// 2). (-3)(a+x) при a=8, x=-10; -3(8-10)=-24+30=6

Answer 2

1) To find the value of 5(a-b) when a = -4 and b = -2, we substitute these values into the expression and perform the calculations:

5(a-b) = 5(-4 - (-2)) = 5(-4 + 2) = 5(-2) = -10

Therefore, when a = -4 and b = -2, the value of 5(a-b) is -10.

2) To find the value of (-3)(a+x) when a = 8 and x = -10, we substitute these values into the expression and perform the calculations:

(-3)(a+x) = (-3)(8 + (-10)) = (-3)(8 - 10) = (-3)(-2) = 6

Therefore, when a = 8 and x = -10, the value of (-3)(a+x) is 6.
