Answer:
The equivalent expression is: (6x + 5)*(6x - 5)
Step-by-step explanation:
This expression is called the difference of two squares.
It has the following format: 
It is factored as: 
In this question:
So
, then 
, then 
So
The equivalent expression is: (6x + 5)*(6x - 5)
No. Say she has a coordinate (3,1)
It can be y=(1/3)x or y=x-2
They can be done either way. So she needs two pairs of values to write an equation.
Answer:
<
Step-by-step explanation:
.174 is greater than .147
Here, Add both the equations in order to eliminate y,
5x = 10
x = 10/5
x = 2
Now, substitute it in 1st equation,
8(2) - 4y = -32
-4y= -32- 16
y = -48/-4
y = 12
In short, Your Answer would be (2, 12)
Hope this helps!
Answer:
4u= - 4i - 24j
u +w = -9i - 3j
Step-by-step explanation:
The question is on operation of vectors
Given u= -i -6j and w= -8i+3j
Then 4u = 4{ -i-6j}
4u= - 4i - 24j
u+w= -i -6j + -8i+3j......................collect like terms
= -i -8i + -6j +3j
= -9i + -3j
= -9i - 3j
