The factors of the polynomial x² + 16x + 48 are ;
-4 and -12.
Given the polynomial :
x² + 16x + 48
To factorize :
x² + 16x + 48 = 0
Two numbers whose addition gives 16 and product gives 48
The two numbers are : 12 and 4
x² + 12x + 4x + 48 = 0
x(x + 12) + 4(x + 12)
Hence,
(x + 12) = 0
(x + 4) = 0
Hence,
x = -4 or x = -12

Answer:
1.C submit ..............................................
Answer:
A
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C (2, - 1) and (x₂, y₂ ) = D (5, 3)
CD = [tex]\sqrt{(5-2)^2+(3-(-1))^2}[/tex]
= [tex]\sqrt{3^2+(3+1)^2}[/tex]
= [tex]\sqrt{9+4^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]

Hi ,I need help. pls?
7(3b-1)=2b-26 please help and give me step by step ☺️
Answer:
b = -1
Step-by-step explanation:
7(3b-1): 7 goes into the numbers by multiplying. This will give you 21b-7.
So now the equation should be like 21b-7=2b-26.
-7 and 2b swap places, making 21b-2b=7-26. It will give you 19b= -19.
Finally divide the two numbers (-19 / 19) and the solution will be b= -1.
If I didn't make a clear answer or a good explanation, please comment. I sometimes mess up my steps, and this is my first time using this.
Answer:
b = -1
Step-by-step explanation:
7(3b -1 ) = 2b - 26
First, distribute.
21b - 7 = 2b - 26
Then, add 7 to both sides AND subtract 2b on both sides
21b - 7 + 7 - 2b = 2b - 2b - 26 + 7
Add common terms
19b = -19
Divide by 19
b = -1
3. In the following formal proof, what is the missing reason?
Answer:
A
Step-by-step explanation:
Start with 2x = 12, and end with x = 6.
To do that, you need to divide both sides by 2.
Answer: A
