Myra combined the like terms in the algebraic expression correctly. Which statement correctly describes what Myra did? 8 x squared + 7 minus 2 x squared + x Myra combined 8 and Negative 2 to equal 6 x squared + x + 7. Myra combined 8 and 2 to equal 10 x squared + x + 7. Myra combined 8 and 7 to equal 15 x squared minus 2 x squared + x. Myra combined 8 and 1 to equal 9 x squared minus 2 x squared + 7.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

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
