Find the missing factor 5y^2-12y+7=(y-1) ( )

The correct answer is 5y-7

Step-by-step explanation:

Given that a quadratic expression is in the form ax²+bx+c where a,b and c are integers, we can factorize as follows

To factorize the expression 5y^2-12y+7, we need to find two numbers that when multiplied we get 5×7, that is ac, and that when added they give us -12 which is b,

these numbers are -7 and -5

therefore, 5y²-5y-7y+7 is our expression

Factorizing we get

             5y(y-1)-7(y₋1)

This gives  (y-1) (5y-7) as the factorized form of 5y²₋12y+7

Therefore the missing factor is 5y-7

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
