Answer:
x = -4 ±√23.
Step-by-step explanation:
x^2 + 8x = 7
(x + 4)^2 - 16 = 7
(x + 4)^2 = 23
x + 4 = ±√23
x = -4 ±√23.
Answer: The correct answer is C.

Answer:
you star from 0 and then go up 4 over 1
Answer:
it means what Y equals what x is plus 4
Step-by-step explanation:
A.2/7
B.7/50
C.3 1/2
D.1 3/5
→ The way I like to do these kind of math problems is below - I find it easier
A fraction usually means to divide, so I will start by dividing the numerator by the denominator of 7/10.
7/10 = 0.7, or, 70%
1/5 = 0.2, or, 20%
Now, we can go and divide each of our answers together.
0.7 ÷ 0.2 = 3.5 :D
Your final answer is 3.5

The value of the verbal expression is -2.
Given that a verbalexpression negative 4 minus negative 2, we need to solve this,
To subtract a negative number, you can rewrite it as adding the opposite. Therefore, "negative 4 minus negative 2" can be rewritten as "negative 4 plus positive 2."
When you add a negative number and a positive number, you can simply combine them by their absolute values and use the sign of the larger number. In this case, the absolute values of 4 and 2 are the same, so the result will have the same sign as the larger number, which is negative.
Therefore, "negative 4 plus positive 2" equals -2.
So, negative 4 minus negative 2 is equal to -2.
