The answer is F=40, when a=10.
Divide 28 by 7, so F=4, when A=1. Then multiply 4 by 10 and you get F=40.
-68hen you enter an equation into the calculator, the calculator will begin by expanding (simplifying)
the problem.
Multiply .15 by 24 to get your answer. The answer would be 3.6 which is $3.60 as your tip
Answer:
x = 4.65 or x = -0.65 (to 2 d.p)
Step-by-step explanation:
To complete the square, use the formula x² + bx + c = (x + b/2)² - (b/2)² + c
- In this case, x² - 8x - 32 = (x - 4)² - 16 - 32
- This simplifies to (x - 4)² - 48 = 0
To solve this:
- First, add 48 to both sides → (x - 4)² = 48
- Next, square root both sides → x - 4 = ± √48 (remember that the square root of a number always has a positive and negative value)
- Finally, add 4 to both sides → x = 4 ± √7
x has 2 solutions
x = 2 + √7 or x = 2 - √7
x = 4.65 or x = -0.65 (to 2 d.p)
Hope this helps!
