the answer is c.
you have to multiply by -3 on both sides to get c on its own.
therefore, c is greater than or equal to -9.
in a, c is less than or equal to 9 so thats not the answer.
In b, c is greater than or equal to 9 but it has to be -9.
in d, c is less than or equal to -9.
the answer is c

Answer:
x = 8
Step-by-step explanation:
In an isosceles right triangle, the side length ratios are ...
1 : 1 : √2 = x : x : 8√2
The latter ratios will match the first ratios when x=8.
__
That is, x = (8√2)/(√2) = 8.
Answer:
5(m + 5) (m - 8)
Step-by-step explanation:
5m2- 15m- 200
Start by pulling 5 out.
5(m^2 - 3m - 40)
We consider all factors of 40
1 40
2 20
4 10
5 8
Based on the middle term we know that 5 and 8 are our best option.
5(m 5) (m 8)
We know the signs have to be one + and one - because a - * - = + and + * + = +
Since 5 - 8 would give us -3 we know that our answer is
5(m + 5) (m - 8)
