The perimeter of a rectangle is (10x2).if it's width is (2x-1),which expression represents the length a.5x-2
b.3x+2
c.8x+3
d.12x+1​

optionC 8x+3 is the answer...

10x+2=2x-1+length

so length= 8x+3

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

squares, rhombus, rectangles
