What would the variables for a and b be? 3/x + 5/x^2 = (ax+b)/x^2

allsm [11]

Answer:

a=3,b=5

Step-by-step explanation:

$\frac{3}{x} + \frac{5}{ {x}^{2} } \\ = \frac{3x}{ {x}^{2} } + \frac{5}{ {x}^{2} } \\ = \frac{3x + 5}{ {x}^{2} }$

so as you got it:

$\frac{(ax + b)}{ {x}^{2} } = \frac{3x + 5}{ {x}^{2} } \\ a = 3 \\ b = 5$

jeka57 [31]

Answer:

Step-by-step explanation:

Plug in 12 for u, 7 for x, and 4 for y in the given expression:

u + xy = 12 + (7)(4)

Remember to follow PEMDAS. First, multiply, and then add:

u + xy = 12 + (7 * 4) = 12 + (28) = 40

40 is your answer.
