2.95 =
(simplifying)
(times by the bottom and add the top)
First you multiply 3 times x and 3 times 2
4(3(x + 2) -1) =50
and get
4( 3x +6 -1) =50
then you add 6 plus -1
4 ( 3x +5) = 50
then multiply 4 times 3x and 4 times 5
12x +20 = 50 and subtract 20 from both sides
-20 -20
and you will get
12x = 30
divided both sides by 12
12x/12 = 30/12
then you find the ones that are the same amount in decimals but are smaller
and that's your answer: x= 5/2
hope you get it!!!
Answer:
A polynomial function that meet the conditions is x³ - 8x² + 5x + 14 = 0
Step-by-step explanation:
Hi there!
Let´s start writting a generic factored function. In this case, the function has 3 zeros so that the factored form will have 3 terms:
(x + a)(x + b)(x + c) = 0
For this expression to be 0, either (x+a) = 0 or (x+b) = 0 or (x+c) = 0
Then:
x + a = 0 ⇒ x = -a
x + b = 0 ⇒ x = -b
x + c = 0 ⇒ x = -c
Then, the values "a", "b" and "c" are equal to the zeros of the function but with opposite sign. Then, in our case:
a = 1
b = -2
c = -7
Then, the polynomial fuction will be:
(x + 1)(x - 2)(x - 7) = 0
Apply distributive property:
(x² - 2x + x -2)(x -7) = 0
(x² - x - 2)(x - 7)
x³ - x² - 2x - 7x² + 7x + 14 = 0
x³ - 8x² + 5x + 14 = 0
Then, a polynomial function that meets the conditions is:
x³ - 8x² + 5x + 14 = 0
Have a nice day!

Since you did not provide any other information, I did some research and might have found the original question/ answer choices. If this is the correct question, then your answer should be D.)
Answer:
x = 95
Step-by-step explanation:
Using the rule of logarithms
• 
x = n ⇔ x = 
Given
(x + 30) = 3, then
x + 30 = 5³ = 125 ( subtract 30 from both sides )
x = 95
