The first 3 are correct but for the last one I’m not sure
Answer:
3 ( x-1) (x+1) is the factored form
zeros are x=1, -1
Step-by-step explanation:
3x^2-3
Factor out a 3
3 ( x^2 -1)
What is inside the parentheses is the difference of squares
( a^2 -b^2) = ( a-b)(a+b)
3 ( x-1) (x+1)
To find the zeros, set this equal to zero
3 ( x-1) (x+1) =0
Using the zero product property
x-1 =0 x+1 =0
x=1, x=-1
Answer:
18 Feet
Step-by-step explanation:
For every 1 inch, the building is 2 feet
There are 9 inches in the building
The equation would be 9 * 2 = 18
Step-by-step explanation:
3x - 2y = 12
Substituting y = 9, we find:
Similarly, solving for point B (4, __) =B (4, 0)
The answer is c because all you are doing here is subbing the variable r for 5b.
