Hi!
Explanation: <em><u>First you had to convert element to fraction is 2=2/1 ,and it gaves us -4/5÷2/1. Then apply to the fraction rules, -4/5 *1/2=-2/5 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie </u></em>
(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:
The answer would be D, or
Step-by-step explanation:
A is 540
B is 30
C is 720
D is 360
Width of the rectangle is 1 unit
Step-by-step explanation:
- Step 1: Let the length of the rectangle be x. Then the width = x - 5. Find dimensions of the rectangle if its area = 6 sq. units
Area of the rectangle = length × width
6 = x (x - 5)
6 = x² - 5x
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0 (Using Product Sum rule to factorize)
x(x - 6) + 1(x - 6) = 0
(x - 6)(x + 1) = 0
x = -1, 6 (negative value is neglected)
x = 6 units
x - 5 = 1 unit
