Answer:31.4166666667
Step-by-step explanation:
Answer: 8
<u>Step-by-step explanation:</u>
log₃ (x² - 32) = log₃ (4x) restrictions: x² - 32 > 0 and 4x > 0 ⇒ x > 4√2
x² - 32 = 4x
x² - 4x - 32 = 0
(x - 8)(x + 4) = 0
x - 8 = 0 or x + 4 = 0
x = 8 or x = -4
<em> -4 does not meet the restriction so not valid</em>

Answer: y = 7x - 6
<u>Step-by-step explanation:</u>
<u> 7x -6 </u>
x² + 0x + 4 ) 7x³ - 6x² + 0x + 7
<u>-7x³ + 0x² - 28x</u>
-6x² - 28x + 7
<u> 6x² + 0x + 24</u>
-28x + 31

Answer: x =
<u>Step-by-step explanation:</u>
ln 3 + ln x = ln 6 + ln (3x - 3) restrictions: x > 0 and 3x - 3 > 0 ⇒ x > 1
ln (3 * x) = ln (6*(3x - 3))
ln (3x) = ln (18x - 18)
3x = 18x - 18
<u>-18x </u> <u>-18x </u>
-15x = -18
x =
> 1 so answer is valid

Answer:
7/10
Step-by-step explanation:
because .7*10 = 70 and it would be 70/100 so you simplify it to 7/10
Answer:
C^2 = a^2 + b^2
The formula for the pythagorem theory
The airplane is 100 feet long because 5*4=20 so
that would mean that 20*5=100
