(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
Answer:
40
Step-by-step explanation:
The common denominator = 5×8
= 40
Answer:
The circumference is also 7 times larger
12 cm radius :2*pi*12= 75.43
12*7=84
84cm radius: 2*pi*84= 528
To check if its indeed 7 times larger: 528/75.43 and you'll get 7
If youre looking for the difference between the two: 528-75.43= 452.57
=3
r=common ratio: 12/6=2; 6/3=2
r=2,
=
*3
plug in 12 for n:
=
*3
=
*3
=2048*3
=6144
The twelfth term in the sequence is 6144
Answer:
Solving equation i and ii, we get;
3x-3y+x+3y=9+12
4x=21
x=21/4
Putting the value of x in equation ii.
(21/4)+3y=12
3y=12-(21/4)
3y=(48-21/4)
y=27/(4*3)
y=9/4
