Answer:
p(x) = x³ - 9x² + 4x + 120
Step-by-step explanation:
complex zeros occur in conjugate pairs
6 + 2i is a zero, hence 6 - 2i is a zero
the factors are therefore (x + 3) , (x - (6 + 2i)), (x - (6 - 2i)), hence
p(x) = (x + 3)(x - 6 - 2i)(x - 6 + 2i)
= (x + 3)((x - 6)² - 4i²)
= (x + 3)(x² - 12x + 36 + 4) ← i² = - 1
= (x + 3)(x² - 12x + 40)
= x³ - 9x² + 4x + 120 ← in standard form
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
The correct answer is didn’t ya because the other ones are not correct
The best method to measure the thickness of a quarter is (C) Centimeters.
This is because the thickness of a quarter is very small and thus bigger units such as meters and kilometers will not be convenient. Centimeters is the best unit.
Answer:
=> 6s
Step-by-step explanation:
Given terms
24s^3 ,12s^4 and 18s
GCF consists of the common factors from all the terms whose GCF has to be found.
In order to find GCF, factors of each term has to be made:
The factors of 24s^3:
24s^3=2*2*2*3*s*s*s
The factors of 12s^4:
12s^4=2*2*3*s*s*s*s
The factors of 18s:
18s=2*3*3*s
The common factors are(written in bold):
GCF=2*3*s
=6s
So the GCF is 6s ..
