Answer:
15.5 weeks (or 15 and a half weeks).
Step-by-step explanation:
Taylor starts at $10.
Each week she makes $20.
Since she already has $10, she only needs to save $310.
310 ÷ 20 = 15.5
Therefore, she will need to save $20 per week for 15 and a half weeks.
It is 30 feet BELOW the platform, so the number is -20 because the platform is 10 feet above ground level.
Her elevation is - 20 because she is 10 feet above ground level, which is 10, and she digs 30 feet down so 10 - 30 is -20.
Hope this helps. :)
Answer:
2(x - 2)(2x + 1)
Step-by-step explanation:
Given
4x² - 6x - 4 ← factor out 2 from each term
= 2(2x² - 3x - 2)
To factor the quadratic inside the parenthesis
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = - 3
The factors are - 4 and + 1
Use these factors to split the x term
2x² - 4x + x - 2 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 1(x - 2) ← factor out (x - 2)
= (x - 2)(2x + 1)
Hence
4x² - 6x - 4 = 2(x - 2)(2x + 1) ← in factored form
Answer:
4:7
Step-by-step explanation:
