Answer:
Multiply both sides by 3, then subtract 6 from both sides
Step-by-step explanation:
d + 6 / 3 = 6 (multiply both sides by 3)
d + 6 = 18 (subtract 6 from both sides)
d = 12
4(3+14c−12d)
=(4)(3+14c+−12d)
=(4)(3)+(4)(14c)+(4)(−12d)
=12+c−2d
=c−2d+12
I am not a hundred percent sure but I think it is A
Hope this helps:)
Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3
52 5/8 because 49 + 3 = 52 and 2/8 + 3/8 = 5/8
