Answer:
3(2 - y)(2 + y)(4 + y²)
Step-by-step explanation:
48 - 3y⁴
Take 3 common:
3(16 - y⁴)
16 is 4² and y⁴ is (y²)²
3(4² - (y²)²)
Using a² - b² = (a - b)(a + b)
3(4 - y²)(4 + y²)
Again, 4 = 2²
3(2² - y²)(4 + y²)
3(2 - y)(2 + y)(4 + y²)
350-215=134, 134/11=12.27, 12.27*20 =245.4, 350-245.4=104.6
104.6 degress F
First derisive the equation for C
I believe the answer is 2(15t).
Complete Question
Sophie pays m dollars to rent a car for the weekend. On the drive home, she buys $45 worth of gasoline. Her friend Melody pays for one-half the cost of the car rental only. Write an expression you could use to determine how much Sophie spent.
Answer:
1/2m + 45
Step-by-step explanation:
We are told in the question that:
On the drive home, she buys $45 worth of gasoline.
Her friend Melody pays for one-half the cost of the car rental only.
Sophie pays m dollars to rent a car for the weekend.
The amount sophie pays for car rental = m - 1/2m
= 1/2m
Therefore, the expression used to determine how much sophie spent is written as:
1/2 × $m + $45
1/2m + 45
