Answer:
x=3X 2 + 5x -6
Step-by-step explanation:
3X2 + 5X-6= 3X2 + 5X 6
X=3X2 +5X -6
Answer:
d) -2
Step-by-step explanation:
(-1 - 19)/(16 - 6)
-20/10 = -2
12 meters because 100 centimeters is equal to one meter.
The house wall, the ground and the ladder form a right triangle, where the ladder is the hypotenuse.
Ladder = sqrt (25^2+10^2) =5sqrt(29)
Answer:
see below
Step-by-step explanation:
Put -1 where x is in each expression and evaluate it.
__
You will find that the expression is zero when the numerator is zero. And you will find the numerator is zero when it has a factor that is equivalent to ...
(x +1)
Substituting x=-1 into this factor makes it be ...
(-1 +1) = 0
__
Evaluating the first expression, we have ...
This first expression is one you want to "check."
You can see that the reason the expression is zero is that x+1 has a sum of zero. You can look for that same sum in the other expressions. (The tricky one is the one with the factor (x -(-1)). You know, of course, that -(-1) = +1.)
