ok
this called f to do
Step-by-step explanation:
1. take a _____
Answer:
x = 3
Step-by-step explanation:
We need it in factorized form to get x.
If the quadratic equation can be divided by a-2 the first part is:
(a-2)
Now to get a², the a must be multpilied by itself. So
(a-2)(a)
To get -10, -2 must be multiplied by 5. So:
(a-2)(a+5)
we can expand to get x
a² + 5a - 2a -10
a² + 3a - 10
a² + ax - 10
x = 3
We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.
According to picture longest side is 18
So this triangle must follow inequality
9+x>18
or 9-9+x>18-9
or x>9
that means value of x must be more than 9.
choices a, c, d are greater than 9 except choice b
Hence choice B-9 is the final answer.
