Answer:
So first, let's substiute the variables into numbers based on your problem. We get -(-1)-(5)^2+3(-1)(5). If we solve that expression, we will get -39. So, your answer is -39. Hope this helps and good luck
Step-by-step explanation:

Answer:
B. x = -6, x = 4
Step-by-step explanation:
The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.
x² +2x +1 = 25
(x +1)² = 25 . . . . . . . rewrite the left side as a square
x +1 = ±√25 = ±5 . . . . take the square root
x = -1 ±5 . . . . . . . . . subtract 1
x = -6 or x = 4
Answer:
x = 25
Step-by-step explanation:
b² + h² = x²
24² + 7² = x²
576 + 49 = x²
625 = x²
√625 = √x²
25 = x
I agree with the answer being B because since it's a common ratio you could just multiply -1/4 with -2 and keep doing that with each new term
3/4 of 6/7. The of means multiplication.
= 3/4 * 6/7. 2 into 4 is 2 and 2 into 6 is 3.
= 3/2 * 3/7 No other number can divide, so we multiply out.
=9/14
That's the answer.
