Answer:

D or 6

Step-by-step explanation:

Angle G is bisected if FGHI is a square. That being the case

7x + 3 = 45          Subtract 3 from both sides

7x = 45 - 3          Combine

7x = 42               Divide by 7

7x/7 = 42/7

Enter the value of a and b that complete the sum: 3/x + 5/x^2 = ax+b/x^2
Aleksandr [31]

Answer:

a=\frac{3}{x^{2} }

b=5

Step-by-step explanation:

we are given

\frac{3}{x} }+\frac{5}{x^{2} }=ax+\frac{b}{x^{2} }

we will compare both sides of equaion

 \frac{b}{x^{2} }=\frac{5}{x^{2} }

comparing both sides we get

b=5

and

\frac{3}{x} }=ax

a=\frac{3}{x^{2} }

hence

a=\frac{3}{x^{2} }

and   b=5
