Answer:
- 2(x - 6)(x - 4)
Step-by-step explanation:
Given
- 2x² + 20x - 48 ← factor out - 2 from each term
= - 2 (x² - 10x + 24) ← factor the quadratic
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 6 and - 4, since
- 6 × - 4 = + 24 and - 6 - 4 = - 10, thus
x² - 10x + 24 = (x - 6)x - 4) and
- 2x² + 20x - 48 = - 2 (x - 6)(x - 4) ← in factored form
Answer:
If we know that 2 angles are complements of each other, then they add up to 90 degrees. Knowing this, if we know that the complement of an angle X has an angle value that is 3 times greater, we can write that as such: X + 3X = 90 => 4X = 90. We solve for X to get: 22.5 degrees.

Step-by-step explanation:
so we got the equation
we solve it and we get:
(we floor the answers)
x = -5.72 -> -5
x = -4.72 -> 4
so:
maximum answer: 4 and 5
minimum answer: -5 and -4
Answer:
80% = 640 and 90% = 720
Step-by-step explanation:
if the highest score is 800
then the 80% score should be
80/100 * 800 = 80 * 8 = 640
so the 80% score is 640
while the 90% score is
90/100 * 800 = 90 * 8 = 720
