Answer:

see explanation

Step-by-step explanation:

Substitute x = - 4 into the equation and solve for h

3(- 4 + h)² = 75 ( divide both sides by 3 )

(- 4 + h)² = 25 ( take the square root of both sides )

-4 + h = ± $\sqrt{25}$ = ± 5

Add 4 to both sides

h = 4 ± 5

h = 4 - 5 = - 1 or h = 4 + 5 = 9

Hence h = - 1, 9

PLEASE HELP QUICK!!......Can someone please solve this and explain how to do it:

Novay_Z [31]

Answer:

A. x = -2.133

Step-by-step explanation:

1. Simplify: $ln(21^{x+3}) = ln(14)\\$

2. Use the formula ( $ln(a^c)=c*ln(a)$ ): $(x+3) * ln(21) = ln(14)$

3. Multiply each term by ln(21): $ln(21)x + 3ln(21) = ln(14)$

4. Move constant to the right: $ln(21)x = ln(14)-3ln(21)$

5. Divide both sides: $x=\frac{ln(14)}{ln(21)}-3$

$x=-2.133$
