A farmer is constructing a second rectangular greenhouse similar to another greenhouse using a scale factor of 2. The first greenhouse has a width of 10 meters, and a length of 20 meters. What is the perimeter of the second greenhouse.

120 meters

Step-by-step explanation:

The first greenhouse has a width of 10 meters, and a length of 20 meters. Since a scale factor of 2 is used, we have to multiply the length and width by 2.

Length of second greenhouse = 20 × 2 = 40

Width of second greenhouse = 10 × 2 = 20

The perimeter of the second greenhouse will then be:

= 2(length + width)

= 2(40 + 20)

= 2 × 60

= 120 meters

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
