What expression is equivalent to 4+ [4x (5-2)] divided by 2

2+6x

Step-by-step explanation:

Is the entire thing divided by 2, if so...

4+(4x(3)) divided by 2

4+12x divided by 2

You can factor the top into 2(2+6x)

so now 2(2+6x) divided by 2

divide top and bottom by 2

answer is 2+6x

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
