Answer:
30
Step-by-step explanation:
We know that in this case, since this is an intersection, the opposite sides are the same. Therefore, we can make a equation like this:
75 = 3x-15
Then we get:
90=3x
30=x
Answer:
One solution
Step-by-step explanation:
Answer:
-16+12= -4
Step-by-step explanation:
When we mins 12 from 16 (16-12) we get 4.
Similarly. When we minus 16 from 12 (12-16) we get -4 because we choose the sign with the greater number.

Substitute:

The area of the shaded region

Answer:
The factors are (x-7) and (x-4)
Step-by-step explanation:
We are finding the factors of a function from the zeros
The zeros are 7 and 4
We can use the zero product property which is
(x-b)(x-c) = 0 where b and c are the zeros
(x-7) (x-4) =0
The factors are (x-7) and (x-4)
