Considering that the expression 5a + 5a + 5ab + 5ab is equivalent to 10a + 10ab, what is an equivalent expression for 6abc + 6abc + 6abc?
a) 18abc
b) 18a + 18b + 18c
c) 18a + 18ab + 18abc
d) 216a + 216b + 216c

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

a.)the line for function b is steeper

for future students the answer is b

hope i
