Expand 8(r + 6) please help !

8r + 48

Step-by-step explanation:

In order to expand brackets you have to multiply everything inside the brackets by the number on the outside.

Therefore:

8 x r = 8r

8x 6 = 48

Put these together and you end up with 8r + 48.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

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
