It’s the first one because it has 7 rows and 7 columns which show that it is 7 times 7 or 7^2.
All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
Answer:
x=0
Step-by-step explanation:
-8x + 2(4x + 2) = 4
Use distributive property to get rid of the parentheses
-8x + 8x + 4 = 4
Add the like terms.
x + 4 = 4
Subtract both sides by four.
x = 0
