Answer:
x =
Step-by-step explanation:
Given
a(x - b) = x ← distribute parenthesis on left side
ax - ab = x ( subtract x from both sides )
ax - x - ab = 0 ( add ab to both sides )
ax - x = ab ← factor out x from each term on the left side
x(a - 1) = ab ← divide both sides by a - 1
x =
Answer:
x, 2, 3
Step-by-step explanation:
The variable is x.
The coefficient(the number multiplied with the variable) is 2
Th constant(the term with no modifiable variables) is 3.
Answer:
-7x-42
Step-by-step explanation:
distribute (-7) to (x+6)
By applying Pythagoras theorem,we get
(hypotenuse)^2=(base)^2+(perpendicular)^2
=>(h)^2=(7)^2+(4)^2
=>(h)^2=49+16
=>(h)^2=65
=>h=√65
Therefore, option B is correct,i.e.,√65
