2*3*4 = 24

b2 - 7b - 6b = -4(-4)2 - 7(-4) - 6 = 16 +28 - 6 = 38

b-4 expression example b = 10 so b-4 = 6

The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).

The algebraic expression is 3(b+5).

You need values for a and b, then you multiply a by 3, b by 2 and add your answers.

b2 - 7b - 6b = -4(-4)2 - 7(-4) - 6 = 16 +28 - 6 = 38

b-4 expression example b = 10 so b-4 = 6

This expression is an example of the Distributive Property. The expression a(b+c) = ab +ac is true because of the Distributive Property.

Evaluate -4(a+b) - 10a/b when a=8 and b=5

There is nothing to "solve". You can evaluate the expression when each of a, b and c are TRUE or FALSE. But that is not solving.

By following BODMAS, evaluate the inner brackets first, collecting terms together as you go: B - 3(B - 4(1 - B)) = 54 → B - 3(B - 4 + 4B) = 54 → B -3(5B - 4) = 54 → B - 15B + 12 = 54 → -14B = 42 → 14B = -42 → B = -3 Check by substituting back into the original equation: B - 3(B - 4(1 - B)) → -3 - 3(-3 - 4(1 - -3)) → -3 - 3(-3 - 4(4)) → -3 - 3(-3 - 16) → -3 - 3(-19) → -3 + 57 → 54 as required.

The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).

3+2*A+B*4/2-4 = 3 + 2A + 2B - 4 = 2A + 2B - 1

Like this . . .B - 4 = 35and it is then an equation, not an expression.
