0.25k + 1.5 − k − 3.5
combining like terms with rational coefficients

-  0. 75 k - 2 .

Step-by-step explanation:

Given  : 0.25k + 1.5 − k − 3.5

To find : Combining like terms with rational coefficients.

Solution : We have given 0.25k + 1.5 − k − 3.5.

On combining like term

0.25 k - k + 1.5 - 3.5.

-  0. 75 k - 2 .

Therefore, -  0. 75 k - 2 .

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
