All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
Answer:
There are no like terms.
Step-by-step explanation:
basically that is your answer you can not solve so it will be 3ax – 3ay – 2bx + 2by
Harry made $10,000 that the end of the year.
The second degree polynomial with leading coefficient of -2 and root 4 with multiplicity of 2 is:

<h3>
How to write the polynomial?</h3>
A polynomial of degree N, with the N roots {x₁, ..., xₙ} and a leading coefficient a is written as:

Here we know that the degree is 2, the only root is 4 (with a multiplicity of 2, this is equivalent to say that we have two roots at x = 4) and a leading coefficient equal to -2.
Then this polynomial is equal to:
