Giving brainliest to correct answer. Reporting false answers. | Dennis has 4 boards. They measure 0.63 meters, 0.38 meters, 0.24 meters, and 0.79 meters. Dennis needs to mend part of the fence that is approximately 1.8 meters in length. When rounded to the nearest tenths, three of the boards will have a sum of 1.8 meters. Which of the three boards will Dennis need to use? Explain your process.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

2 x t divided by n

step-by-step explanation:

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.
