A carpenter is making a backyard deck in the measurements, he has determined that he needs to make a support triangle with an area 40m ^ 2 He knows that the base must be 3 less than 2 times the height the base is represented by 2x - 3 and height equals . Find the equation that correctly shows the area of the triangle.

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

the 3rd on is correct

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
