How do you find the solution of this proportion?<br> 4/9 = m2-1/54 <br> m2 is m to the power of 2
elena-14-01-66 [18.8K]

Answer:

±5sqrt(6)/6 = m

Step-by-step explanation:

4/9 = m^2-1/54

Add 1/54 to both sides

4/9+ 1/54 = m^2-1/54 +1/54

4/9+ 1/54 = m^2

Get a common denominator of 54

4/9 *6/6 + 1/54 = m^2

24/54 + 1/54 = m^2

25/54 = m^2

Take the square root of each side

±sqrt(25/54) = sqrt(m^2)

±sqrt(25/54) = m

±sqrt(25)/sqrt(54) = m

±sqrt(25)/sqrt(9)sqrt(6) = m

±5/3sqrt(6) = m

±5/3sqrt(6) *sqrt(6)/sqrt(6) = m

±5sqrt(6)/3*6 = m

±5sqrt(6)/6 = m

If a=5x^2+3x-7 and b=-3x^2-7x+5 find b-a
uranmaximum [27]

Answer:

-8x^2-10x+12

Step-by-step explanation:

first set up the problem:

(-3x^2-7x+5)-(5x^2+3x-7)

Since you are subtracting you need to distribute the (-) sign:

(-3x^2‐7x+5)(-5x^2-3x+7)

Now just combine like terms

-3x^2+(-5x^2= -8x^2

(-7x+(-3x= -10x

5+7= 12

set answer in standard form:

-8x^2-10x+12
