Evans spends 4/5 on comics because he put 15 in his account because 30 / 2 is 15 then i did 3 x 5 = 15, so he spent 1/5 witch is 3$ and then ther is 12 left so he buys 4 comics 4 x 3 = 12

The first part of the question is not needed 
we only need to know M1 and M2
(y2-y1)^2+(x2-x1)^2=(your answer)^2
(5-16)^2+(-3-2)^2=(your answer)^2
(-11)^2+(-5)^2=(your answer)^2

Write the form of the partial fraction decomposition of the rational expression. Do not solve for the constants. 5x − 4 x(x2 + 7
Nikitich [7]

Answer:

\frac{5x-4}{x(x^2+7)^2}  = \frac{A}{x} + \frac{Bx+C}{x^2+7} + \frac{Dx+E}{(x^2+7)^2}

Step-by-step explanation:

Given the expression \frac{5x-4}{x(x^2+7)^2}, we are to re-write the expression in form of a partial fraction.

Before we write in form of a partial fraction, we need to note the expression at the denominator. <u>Since the expression in parenthesis is a quadratic equation, the equivalent numerator must be a linear expression.</u>

<u />

<u>Also the quadratic equation is a repeated form since it is squared</u>. This means that we are to repeat the quadratic equation twice when writing as a partial fraction.

\frac{5x-4}{x(x^2+7)^2}  = \frac{A}{x} + \frac{Bx+C}{x^2+7} + \frac{Dx+E}{(x^2+7)^2}

From the above partial fraction, <em>it can be seen that x² + 7 in parenthesis was repeated twice and their equivalent expressions at the numerator are  both linear i.e Bx+E and Dx+ E where A, B, C, D and E are the unknown constant.</em>
