Answer:
X = 2 or X = -10
Step-by-step explanation:
We know either3x+12=18or3x+12=−18
3x+12=18(Possibility 1)
3x+12−12=18−12(Subtract 12 from both sides)
3x=6
3x
3
=
6
3
(Divide both sides by 3)
x=2
3x+12=−18(Possibility 2)
3x+12−12=−18−12(Subtract 12 from both sides)
3x=−30
3x
3
=
−30
3
(Divide both sides by 3)
x=−10
Answer:
x=2 or x=−10
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.
A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.
The dimensions of the original photo is 6 x 6.

The possible outcomes of the first part are (QQ,NN,QN,NQ) so there are 4 outcomes.
For the second one 5/8 the the probabliity
Answer:
V = 2,495.5 ft³
Step-by-step explanation:
Volume of the given cylinder = πr²h
Where,
π = 3.14
radius (r) = ½(17) = 8.5 ft
height (h) = 11 ft
Plug in the values into the formula
V = 3.14 × 8.5² × 11
V = 3.14 × 72.25 × 11
V = 2,495.515
V = 2,495.5 ft³ (to nearest tenth)
