Answer:
(x - 12)(x² - 2)
Step-by-step explanation:
Given
x³ - 12x² - 2x + 24 ( factor the first/second and third/fourth terms )
= x²(x - 12) - 2(x - 12) ← factor out (x - 12) from each term
= (x - 12)(x² - 2)
-3, -1, 1, 3, 5 would be five of them.
Answer:
64
Step-by-step explanation:
Its practically just 8 times 8
Because each of these angles are 90 degrees, we know they're each equal to each other.
Let's find the value of the variable y first.
We can use 5y - 17 = 2y + 50 to find the value of y.
5y - 17 = 2y + 50
-2y from both sides
3y - 17 = 50
+17 to both sides
3y = 67
Divide both sides by 3
y = 22.33
Now we need to find the value of x.
x + 44 = 7x - 248
-x from both sides
44 = 6x - 248
+248 to both sides
292 = 6x
Divide both sides by 6
x = 48.67
And there's your variables.
y = 22.33
x = 48.67
My graphing calculator computes the best match to a cubic function, which predicts mileage of about 39.7 mpg at 65 mph.
The second-best match is to a quadratic function, which predicts mileage of 29.8 mpg at 65 mph.
Linear regression predicts mileage of about 36.6 mpg at 65 mph.
It appears the best choice of those offered is (D) about 36 mpg.
