Answer:
a y = 2
b.y = 14
c. y =56
Step-by-step explanation:
a .6 (1)- 4=2
y=2
b. 6 (3)- 4
=18-4
y=14
c. 6 (10) - 4
= 60 - 4 =56
Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)
456=40w+4w^2+100w
456=4w^2+140w
114=w^2+35w
0=w^2+35w-114
find what 2 numbers multiply to get 114 and add to get 35 and factor
-3 and 38
0=(w-3)(w+38)
set each to zero
w-3=0
w=3
Density = mass / volume
Givens
Density = 13.6 grams / cm^3
mass = 47 grams.
Solve
D = m/v
13.6 = 47 / volume Multiply by volume
13.6 * volume = 47 Divide by 13.6
volume = 47 / 13.6
Volume = 3.46 ccs
Answer:
2
Step-by-step explanation:
Pretend there is no decimal point. We can do this by multiplying both numbers by 10.
After that, it becomes 68/34. You then divide those two, and you get 2 as your answer.
