(Please answer quick!!) -3(x + 4) – 5(x + 3) is equivalent to -8x+27:
Step 1: -3x+12-5x+15
Step2: -3x+-5x + 12 +15
Step 3: the student made a mistake
I’m which step did the student first make a mistake, and what is a correct expression for that step?
A step 1; -3x + 1 - 5x - 2
B step 1; -3x - 12 - 5x - 15
C step 3; -2x + 27
D step 3; 2x + 27

the answer is b.

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

0.038
