Answer:
the correct solution is letter A.
Step-by-step explanation:
We have the following expression:
6sqrt(7) - 5x*sqrt(7) - x*sqrt(7)
Grouping the expression, we have:
=sqrt(7)*[6 - 5x - x]
=sqrt(7)*[6 - 6x]
= 6*sqrt(7)- 6x*sqrt(7)
So the correct solution is letter A.
Answer:
no solutions
Examples:
2 = 2 is infinite solutions
x = 2 is one solution
2 = 0 is no solution
Well,
8 + 6q + q
We could be lazy and not simplify this. Thus, we would say:
"Eight plus 6 times a number q plus q."
Or, we could be smart, collect like terms, and say:
"Eight plus 7 times a number q."
Answer:
a = 
Step-by-step explanation:
Given
ai + bj and 5i - 2j are perpendicular and b = 3, that is
ai + 3j and 5i - 2j are perpendicular, then
The scalar product = 0 , that is
5a - 6 = 0 ( add 6 to both sides )
5a = 6 ( divide both sides by 5 )
a =
The answer would be negative fifty two
-52
X+58=6
58-6=52
So the answer would be negative 52
