7) Find the solutions to the following polynomial: 5x* +5x2 – 10 = 0

Step-by-step explanation:

We want to solve the quadratic equation:

Rewrite in standard form to get:

Divide through by 5 to get;

Factor to get;

Apply zero product property to get:

The solutions are:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
