Landon used a semicircle, a rectangle, and a right triangle, to form a figure below. which is the best estimate of he area of the figure in square centimeters?

answer:

the point lies 1 unit below the regression line.

step-by-step explanation:

the residual is the actual value minus the predicted value.

so the residual of -1 means the point lies 1 unit below the regression line.

answer:

choice a is correct answer.

step-by-step explanation:

given expression is :

3x²+18x+24

we have to represent above expression in factored form.

as we have noticed that the expression contains the multiples of 3.

taking 3 as common from given expression,we get

3(x²+6x+8)

now, spit the middle term of above expression so that the product of two terms should be 8 and their sum be 6.

3(x²+4x+2x+8)

making two groups and taking two terms as common,we get

3(x(x+4)+2(x+4))

taking (x+4) as common,we get

3(x+4)(x+2) which is the factored form of 3x²+18x+24.

answer: 270÷90=3=30% have and 70% don't have a computer.
