The width of a rectangle is 7t - 1.5 feet and the length is 1.5t + 5 feet. Find the perimeter of the rectangle.

P = 17t + 7

Step-by-step explanation:

P = 2L + 2w

L = 1.5t + 5

w = 7t - 1.5

P = 2*(1.5t  + 5) + 2*(7t - 1.5)

P = 3t + 10 + 14t - 3

P = 17t + 7

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
