BRAINLIEST Multiply each side by the common denominator

Dovator [93]

Answer:

c. x² + 2x -5 = 0

Step-by-step explanation:

Given expression;

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

Unknown:

The quadratic equation equivalent to this expression:

Solution:

The common denominator here is 3x;

So, multiply both sides by 3x

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

5 x 3 = (x + 2)x

15 = x² + 2x

So;

x² + 2x - 15

The quadratic expression is x² + 2x - 15

gurindas previous checking account balance was $532.14. since then she has written a check for $46.19 and one for 138.32. she al

RUDIKE [14]

Answer:

$541.63

Step-by-step explanation:

To find the balance of Gurindas, we need to break down our values.

Checking Balance = $532.14

Checks = $-46.19 + $-138.32 = $-184.51

Deposit = $200

Service Charge = $-6

Now to find her new balance, we simply add them all together.

New Balance = 532.14 + -184.51 + 200 + -6

New Balance = $541.63

Answer:

Step-by-step explanation:

$a(x)=x^3-3\\b(x)=2x+1\\c(x)=\frac{3}{x+2} \\d(x)=4-x\\a.\\a(4)=4^3-3=64-3=61\\b.\\\\c(x-5)=\frac{3}{x-5+2} =\frac{3}{x-3} \\c.\\d(-1)=4-(-1)=4+1=5\\b(d(-1))=b(5)=2(5)+1=11\\\\d.\\(coa)(2)=c(a(2))=c(2^3-3)=c(8-3)=c(5)=\frac{3}{5+2} =\frac{3}{7}$
