Step-by-step explanation:
number of correct answer is x and
number of wrong answer is y
according to question
In the case of Radhika
5x-2y=30
x=10
y=10
In the case of Jay
5x-2y=-12
x=4
y=16
incorrect answer by Radhika is 10 and by jay is 16
Answer: Yes
Step-by-step explanation: The answer of 1400 is correct.
What I did is I found the area of the figure assuming it was a rectangle, then I subtracted the corners that were removed.
1800 - 150 - 100 - 150 = 1400
X=6 and x=-8
To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.
Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
<h2>Hey there!</h2>
<h2>Given,</h2>
length = 2x-5 and breadth(width) = x+9
<h3>We know that:</h3><h3>Perimeter of a Rectangle is = 2*(l + b)</h3>
= 2*(2x-5 + x +9)
= 2*(x+4)
= 2x + 8
<h3>So, the perimeter of the given rectangle is = 2x + 4</h3><h3 /><h2>Hope it help you</h2>
