Answer:
Values for x = -1 + 7i and -1 - 7i
Step-by-step explanation:
we have an equation,
(x+1)^2 = -49
We need to solve this equation for all values of x:
(x+1)^2 = - 49
Taking square root both sides
√((x +1)^2) = √-49
x + 1 = ± 7i
Subtract both sides by 1
x = -1 ± 7i
Hence we get two values for x = -1 + 7i and -1 - 7i
Answer: 6.25 IF my assumption is correct about the missing x!
The Other way around: 4.5 with 2x² + y² / 3
Step-by-step explanation: 2y² + y² / 3 assuming the 2nd y should have been x, 1st y is y, and all divided by 3
2(3)² + (1.5)² / 3
2(9) + 2.25 /3
18 + 2.25 /3
20.25/3
6.25
Edited to correct!________ OR 2y² + y² / 3 assuming the 1st y should have been x, 2nd y is y, and all divided by 3
2(1.5)² + (3)² / 3
2(2.25) + 9 / 3
4.5 + 9 /3
13.5 /3
4.5
Answer:
Step-by-step explanation:
y=x+9
10+2x=-2(x+9)
10+2x+2x+18=0
4x=-28
x=-7

Answer:
Since a fraction represents a division, we should do that division to know what the value of a fraction is. The larger numerator, the larger the value of the fraction will be; and the larger denominator, the smaller the fraction will be. ...
