Question

-220:(-36+14)*11-8= (6x-12)*(x-0,4)=0

Answer 1

Пошаговое объяснение:

-220 : (-36 + 14)11 - 8 = - 220 ÷ (- 22)11 - 8 = 110 - 8 = 102

(6x - 12)(x - 0,4) = 0

6х - 12 = 0 х - 0.4 = 0

х = 2 х = 0.4

Ответ : х₁ = 0.4 ; х₂ = 2

Answer 2

To solve the equation -220 = (-36 + 14) * 11 - 8, you can follow these steps:

Step 1: Simplify the equation inside the parentheses: -220 = (-22) * 11 - 8

Step 2: Perform the multiplication and subtraction: -220 = -242 - 8

Step 3: Continue simplifying the equation: -220 = -250

The equation -220 = -250 is not true; there is no solution in this case.

Now, let's solve the equation (6x - 12) * (x - 0.4) = 0. To find the values of x that make this equation true, you can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, you have two factors:

1. 6x - 12
2. x - 0.4

Set each factor equal to zero and solve for x:

1. 6x - 12 = 0 Add 12 to both sides: 6x = 12 Divide by 6: x = 2

2. x - 0.4 = 0 Add 0.4 to both sides: x = 0.4

So, the solutions for the equation (6x - 12) * (x - 0.4) = 0 are x = 2 and x = 0.4.
