Answer:
Step-by-step explanation:
Begin the solution by squaring both sides of the given equation. We get:
(3x - 4)^2 = 2x^2 - 2x + 2, or:
9x^2 - 24x + 16 = 2x ^2 - 2x + 2
Combining like terms results in:
7x^2 - 22x + 14 = 0
and the coefficients are a = 7, b = -22, c = 14, so that the discriminant of the quadratic formula, b^2 - 4ac becomes (-22)^2 - 4(7)(14) = 92
According to the quadratic formula, the solutions are
-b ± √discriminant -(-22) ± √92 22 ± √92
x = ------------------------------- = ----------------------- = ------------------------
2a 14 14
Molly got 20 because she did not follow the order of operations, so this is incorrect. Nancy got the correct answer because she multiplied 4 * 3, and then added 2, giving her 14. Molly added 3+2, and multiplied that by 4. Nancy is correct with 14.
Si, es cierto. Si, es cierto.
I would say 63 deer because 35 + 28 is close to being 65 so idk but I’m gonna say it’s 63 feet
Answer:
x = 3.7
Step-by-step explanation:
Reference angle = 24°
Hypotenuse = 4
Side adjacent to reference angle = x
We would apply the trigonometric ratio, CAH, which is:
Cos 24 = adj/hyp
Cos 24 = x/4
4 × Cos 24 = x
x = 3.65418183 ≈ 3.7 (to nearest tenth)
