Step-by-step explanation:

  • You can use the distributive formula to answer:

a(b - c) = ab - ac

2(3x - 1) - 3x + 4

6x - 2 - 3x + 4

  • Simplify by the common terms:

3x + 2

That is the answer

Hope that helped!!

-2y-4=4(y-1) how do i solve this?
forsale [732]

Answer:

y = 0

Step-by-step explanation:

- 2y - 4 = 4 (y - 1)

- 2y - 4 = 4y - 4

- 2y - 4y = - 4 + 4

- 6y = 0

- y = 0/6

- y = 0

y = 0

<h3>Answer:   2072.4 square cm</h3>

===============================================================

Explanation:

If you used scissors to cut a vertical slice down the lampshade, then it can be unrolled to form a rectangle.

The horizontal portion of this rectangle is the distance around the circle, which is the perimeter of the circle, or the circumference. That's C = 2pi*r. Check out the diagram below to see what I mean.

The diagram shows that the diameter is 20 cm, so the radius is half that at 20/2 = 10 cm.

The circumference is C = 2*pi*r = 2*pi*10 = 20pi cm exactly

The height of the rectangle is the height of the cylinder, which is h = 30 as shown in the diagram.

The area of the rectangle is length*height = (20pi)*(30) = 600pi square cm exactly.

If we were to use something like pi = 3.14, then its approximate area is 600*pi = 600*3.14 = 1884 square cm

Let's bump this up by 10%. To do so, we'll multiply by 1.10

1.10*1884 = 2072.4

A fair die is rolled four times. Find the probability that all four rolls show different numbers
tensa zangetsu [6.8K]

Number of such outcomes, in which each number is no less than the preceding number, will be equal to number of ways of selecting 4 numbers from 6, with replacement; without considering order!


Why?


Lets choose any such set of size 4, say {2, 1, 1, 3}. we can sort it to get a sequence {1,1,2,3} which is one of our desired outcomes. So each such sorted sequence corresponds to one selection of size 4, with replacement and without considering order.


Number of such selections will be equal to number of solutions of following equation:


x1 + x2 + x3 + x4 + x5 + x6 = 4


where:


x1: number of 1 in the selections


x2: number of 2s in the selection


.


.


x6: number of 6s in the selection


Number unique solutions of such equation = 9 choose 5 = 126


(For more details on this see : Unordered sampling with replacement )


Number of possible outcomes = 6^4 = 1296


Probability of favorable outcomes = 126/1296=7/72

Formulas A=bh/2 A=bh and I have 6in 4in 6in 10in and I have to find the area
Naddik [55]

Answer:

Lots of "ifs" here.

A=bh/2 is the formula for the area of a triangle.

A=bh is the formula for the area of a rectangle or a parallelogram.

If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2

If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2
