X= -2
put x+3=-2x-3
+3. +3
x+6=-2x
-x. -x
6= -3x
/3. /3
x=-2
A solution is where the graph crosses the x axis (when y=0). Since the graph never touched the x axis, there is no solution.
Answer:
There are 25 of 2/5 of a foot pieces in 10 feet.
Step-by-step explanation:
1. Divide 10 by 2/5
2. The answer is 25.
Exponent of a number says how many times.
2³
The 2 is the base number, while the little 3 is the exponent.
2³ = 2 x 2 x 2 = 8
Basically, you would just have to do two, three times.
Very time when you get the hang of it !!
(x+5)(x-5)
= x^2 - 5x + 5x - 25
= x^2 - 25
(5x+3)(5x-3)
= 25x^2 - 15x + 15x - 9
= 25x^2 - 9
do you see the pattern? both the coefficient on x and constant multiply together to make a perfect square and the middle term, also known as "b" term cancels out leaving a binomial
