Randy divides (2x4 – 3x3 – 3x2 + 7x – 3) by (x2 – 2x + 1) as shown below. What error does Randy make? x squared minus 2 x + 1 St
artLongDivisionSymbol 2 x Superscript 4 Baseline minus 3 x cubed minus 3 x squared + 7 x minus 3 EndLongDivisionSymbol. minus 2 x Superscript 4 Baseline minus 4 x cubed + 2 x squared to get a remainder of x cubed minus 5 x squared + 7 x. minus x cubed minus 2 x squared + x to get a remainder of negative 3 x squared + 6 x minus 3. minus negative 3 x squared + 6 x minus 3 to get a remainder of 0 and a quotient of 2 x squared + x + 3. He makes a subtraction error. He makes an error writing the constant term in the quotient. He makes an error choosing the x-term in the quotient. He makes an error rewriting the problem in long division.

here we have given that number of bees visit a plant id 500 times the number of years that the plant is alive.
we know that t is the number of years that plant is alive.
we know that is expression representing the number of bees that will visit the plant in its life time.
The complete question in the attached figure
we know that
angle y and angle (5y-18) are supplementary angles
then
y°+(5y-18)°=180°------> 6y=180+18------> y=198/6-----> y=33°
and
angle x and angle y are also supplementary angles
then
x+y=180--------> x=180-y-----> x=180-33-----> x=147°
the answer is
x=147°
y=33°
