ПОМОГИТЕ СРОЧНО ПЛИИИИИЗ Раскройте скобки и приведите подобные слагаемые: -2(1,8m+4)-2,4m+9

Answer 1

= - 3,6m - 8 - 2,4m + 9 = -(3,6m + 2,4m) + (9 - 8) = -6m + 1

Answer 2

-2x1,8m+4x(-2)-2,4m+9=-3,6m-8-2,4m+9=(-3,6-2,4)m+1=-6m+1=1-6m

Answer 3

Solving the Expression -2(1.8m + 4) - 2.4m + 9

To solve the given expression and simplify it, we'll start by applying the distributive property to the expression -2(1.8m + 4) and then combine like terms.

Step 1: Apply the distributive property -2(1.8m + 4) can be expanded as -2 * 1.8m - 2 * 4.

Step 2: Combine like terms After applying the distributive property, we'll combine like terms in the expression.

Applying the Distributive Property

-2(1.8m + 4) = -2 * 1.8m - 2 * 4 -2(1.8m + 4) = -3.6m - 8

Now, the expression becomes: -3.6m - 8 - 2.4m + 9

Combining Like Terms

Combining like terms, we get: -3.6m - 2.4m - 8 + 9 -6m + 1

So, the simplified form of the given expression -2(1.8m + 4) - 2.4m + 9 is -6m + 1.
