Answer:
The area of a rectangle is 520 square inches. The length is 3 more than twice the width. The equation 520 = 2w2 + 3w can be used to find the length and width of the rectangle.
Step-by-step explanation:
1st statement:
l= 2w+3
A= l × w
520= w×(2w+3)
520= 2w²+ 3w
2nd statement:
length of fencing= w+2l
120= w+2l
l= 60-w/2
A= (60-w/2) × w
A= 60w- w²/2
Hence this statement is incorrect
3rd statement:
H= x
B= x-4
P= x-2
Accoriding to pythagoras theorem
H²=P²+B²
x²=(x-4)²+(x-2)²
x²= x²-8x+16 + x²-4x+4
0= x²-12x+20
Hence this statement is incorrect
4th statement:
two consecutive even numbers are given by n and n+2
So this statement is incorrect
