(1)
we are given

we can use quadratic formula


now, we can compare and find a , b and c
we get

now, we can plug these values into quadratic formula


we can simplify it



so, we will get solution
{−3+i, −3−i}.........Answer
(2)
we are given equation as

Since, Jamal solve this equation by completing square
so, firstly we will move constant term on right side
so, subtract both sides by 14


we can write

so, we will add both sides by 4^2

we get
..............Answer
The correct answers are A. 2x= 40 and D. 4x= 80~
A. 2*20= 40
D. 4*20= 80
Hope this helps~
For 12 Pounds (= 12 * 16 = 192 Ounce), it costs = 18.75
So, for 1 Ounce, it would be: 18.75 / 192 = 0.097
In short, Your Answer would be: $0.097
Hope this helps!
Answer:
1. c) Add/ Subtract the same quantity to/from both sides
2) Yes
Step-by-step explanation:
Answer two questions about Equations A and B:
A. 3x – 1= 7
B. Зx = 8
1) To get Equation B from Equation A we need to take the following steps
A. 3x – 1 = 7
We add one to both sides
3x - 1 + 1 = 7 + 1
3x - 0 = 8
3x = 8
Option c is the correct option.
2) We are given Equations:
A. 3x – 1= 7
B. Зx = 8
3x - 1 = 7 = 3x = 8
3x = 7 + 1 = 3x = 8
3x = 8 = 3x = 8
Therefore, we can say, Yes, Equation A is equivalent to Equation B, hence they have the same solution.
