Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= ![\[2* [(5 + 2y) + (10 + 4y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%285%20%2B%202y%29%20%2B%20%2810%20%2B%204y%29%5D%5C%5D)
Simplifying,
= ![\[2* [(15+6y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%2815%2B6y%29%5D%5C%5D)
= ![\[(30+12y)\]](https://tex.z-dn.net/?f=%5C%5B%2830%2B12y%29%5C%5D)
Hence the perimeter of the rectangle is given by (30 + 12y)
Answer:
6/15-3/10
Step-by-step explanation:
3x2/15=6/15
Y=csc(x)+2
(Took the test on edge)
The problem cannot be fully solved because you did provide the line on which the line is parallel/ but i can give you the steps on how to solve it. first solve the slope of the parallel line by
m = ( y2 - y1 ) / ( x2 - x1 )
then the slope of that line is equal to slope of line passing pooint ( -1 , 1)
then solve the y intercept of the line using
y = mx + b
where b is the y intercept
then you will have the equation of the line
Answer:
-7
Step-by-step explanation:
A = 3
3×3 = 9
B= -4
-4 × -4 = 16
9 - 16 = -7
