d) neither parallel or perpendicular
(2+1)+3=2+(2+2)
Any two numbers that add to 4.
It would be 9 because 2 x 3 = 6 and then 6 + 3 = 9
Answer:
The width of the rectangle is 75 meters and length is 480 meters.
Step-by-step explanation:
The perimeter of the rectangle = 1110 meters
Let the width of the rectangle = k meters
So,the length of the rectangle = 6k + 30
Now, PERIMETER OF A RECTANGLE = 2(LENGTH + WIDTH)
⇒ 1110 = 2( k + (6k + 30))
or, 1110 = 14 k + 60
or, 14 k = 1110 - 60 = 1050
⇒ k = 1050/14 = 75
Hence, the width of the rectangle is k = 75 meters
and the Length of the rectangle is 6k + 30 = 6(75) +30
= 480 meters
X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
