I need help fast! Answer and explanation please! (see attachment) Solve for x, show your work.
Inessa05 [86]

Answer:

x = -5/2

Step-by-step explanation:

3 ^ ( 4x-5) = (1/27) ^( 2x+10)

Rewriting 1/27 as 3^-3

3 ^ ( 4x-5) = (3^-3) ^( 2x+10)

We know that a^b^x = a^(b*c)

3 ^ ( 4x-5) = (3) ^(-3*( 2x+10))

3 ^ ( 4x-5) = (3) ^( -6x-30)

The bases are the same so the exponents are the same

4x-5 = -6x-30

Add 6x to each side

10x -5 = -30

Add 5 to each side

10x -5+5 = -30+5

10x = -25

Divide each side by 10

10x/10 = -25/10

x = -5/2

Solve: s = 4 + √ s + 2<br><br> a. s=2<br> b. s=7<br> c. s=2 or s=7<br> d. no real solution
lyudmila [28]

Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)


Square both sides: s^2 - 8s + 16 = s + 2


combine like terms: s^2 - 9s + 14 = 0


Factor this: (s-7)(s-2)=0


Solve for s: s={7, 2}
