the value of c that makes the expression a perfect square binomial is c=4 .
<u>Step-by-step explanation:</u>
Here we have , an expression x2 + 4x + c or , 
. We need to find the value of c that makes the expression a perfect square binomial. Let's find out:
We have ,
⇒ 
⇒ 
Now , we know that 
Comparing above equation , to we get ;
⇒ { 
}
⇒ 
⇒ 
Therefore , the value of c that makes the expression a perfect square binomial is c=4 .
Answer:
a) P = (-3, 4, 3)
b) P = (7, 4, 1)
Step-by-step explanation:
a) You want Q-P = (5, 4, -1) where Q = (2, 0, 2). Solving for P, we get ...
P = Q - (5, 4, -1) = (2-5, 4-0, 2-(-1))
P = (-3, 4, 3)
__
b) The vector in the opposite direction of the one given is the given one multiplied by -1.
P = Q - (-1)(5, 4, -1) = (2+5, 0+4, 2-1)
P = (7, 4, 1)

Answer:
Surface area of a cube = 384 mm²
Step-by-step explanation:
Surface area of a cube = 6 s²
Where
s = side length of the cube
s = 8 mm
Surface area of a cube = 6 s²
= 6 * 8²
= 6 * 64
= 384 mm²
Surface area of a cube = 384 mm²
