] L Which change can be made to correct the chart? Chin made an error in his chart showing the multiplication of the binomial by the trinomial. (3x+y)(x²+2y+4) O The expression 3x3 should be 3x2. O The expression 6x should be 6xy. O The expression xạy should be x?y2. O The expression 4y should be 4y?. x2 2y 4 3x 3x3 6x 12x y у xy 2y? 4y​

answer: x=3 and y=4

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
