For what ordered pair (a, b) are there infinite solutions (x, y) to the system 4x + ay = -8,
2x + y = b.

(2, -4)

Step-by-step explanation:

The second equation should be half of the first equation.

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
