Slip and slide method
3y^2-16y+16
Multiply a by c value and replace as shown below
y^2-16y+48
Factor normally
(y-12)(y-4)
Divide both numbers by the previous a value
(y-12/3)(y-4/3)
(y-4)(y-4/3)
Because -4/3 does not become a whole number change the three to become the coefficient of y
(y-4)(3y-4)
Check by foiling
Final answer: (3y-4)(y-4)

Find the distance between the two points rounding to the nearest tenth (if
Olin [163]

Answer:

d=9.2

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(1-8)^2+(1-(-5))^2}

d=\sqrt{(-7)^2+(1+5)^2}

d=\sqrt{49+(6)^2}

d=\sqrt{49+36}

d=\sqrt{85}

d=9.21954

d=9.2

Answer:

<h2>x=-2 or x=8</h2>

Step-by-step explanation:

Isolate by the x from one side of the equation.

|x-3|=5

x-3=-5 and x-3=5

1. x-3=-5

Add 3 from both sides.

x-3+3=-5+3

Solve.

-5+3=(-2)

x=-2

2. x-3=5

Add 3 from both sides.

x-3+3=5+3

Solve.

5+3=8

x=8

Therefore, the correct answer is x=-2 or x=8.

the number of buckets of paint n needed to paint a wall varies jointly with the total area a and the thickness t of the wall, an
Nat2105 [25]
The number of buckets is directly proportional to the area and the thickness of the wall and inversely proportional to the amount of paint. Mathematically, we can write:

n = k · (a · t) / p

where k is the proportionality constant which we do not know.

We can calculate k with the given data: 5 2-gallon buckets, area of 100 square feet and thickness 3 inches:

k = (n · p) / (<span>a · t)
   = (5 </span>· 2) / (100 · 3) = 0.0333

Now that we know the constant, we can calculate the area that can be painted with 8 2-gallon buckets if the thickness is 6 inches:

a =  (n · p) / (k<span> · t)
   = (8 </span>· 2) / (0.0333 · 6)
   = 80 ft²

Please, note that we made sure to have the exact same units of measurements than the previous case.

Therefore, the correct answer is an area of 80 ft².
