Question

А)44х+13х-х= б)5а*6b*20*4c= b)14(6+y)=

Answer 1

А)44х+13х-х=56х; б)5а×6b×20×4c=24000abc; c)14×(6+y)=84+14y.

Answer 2

a) To solve the equation 44x + 13x - x = 0, we can combine like terms on the left side of the equation:

44x + 13x - x = (44 + 13 - 1)x = 56x

So the equation simplifies to:

56x = 0

To solve for x, we divide both sides of the equation by 56:

56x/56 = 0/56

x = 0

Therefore, the solution to the equation is x = 0.

b) To simplify the expression 5a * 6b * 20 * 4c, we can multiply the numbers together and combine the variables:

5a * 6b * 20 * 4c = (5 * 6 * 20 * 4) * (a * b * c)

= 2400 * (a * b * c)

So the simplified expression is 2400 * (a * b * c).

c) To simplify the expression 14(6 + y), we distribute the 14 to both terms inside the parentheses:

14(6 + y) = 14 * 6 + 14 * y

= 84 + 14y

Therefore, the simplified expression is 84 + 14y.
