(2x + 2)/y = 4w + 2
× y
2x + 2 = y(4w + 2)
2x + 2 = 4wy + 2y
- 2
2x = 4wy + 2y - 2
÷ 2
x = 2wy + y - 1

So your answer is the second option, I hope this helps!

Alfredo's painting his storage shed. He won't paint the top or bottom of the shed so he needs to calculate the lateral surface a

slavikrds [6]

Answer:

He is not painting the bottom or top meaning that he will paint 4 sides total, when there is a rectangular prism there are 6 sides and 3 pairs of 2 equal sides, so since there is a wall that is 9ft x 7 ft there is two of those, and since there is a wall that is 12 ft x 7 ft there are two of those as well. meaning that (7x9)·2=126 and (12x7)·2=168 when added we get 294. meaning that he needs to paint an area of 294 ft

The hypotenuse of a right triangle is 6 cm and one side is 2 cm longer than the other side. Find the length of each side to one

MA_775_DIABLO [31]

Answer:

The two legs of the right triangle are approximately 3.1 cm and 5.1 cm and the hypotenuse is 6 cm.

Step-by-step explanation:

Let x be one leg of the right triangle.

Since the other leg is two centimeters longer, it can be represented by the expression:

$x + 2 \text{ cm}$

According to the Pythagorean Theorem, for a right triangle:

$a^2 + b^2 = c^2$

Where c is the hypotenuse and a and b are the two legs.

The hypotenuse is given to be 6 cm and the two legs are x and (x + 2). Hence:

$(x)^2 + (x+2)^2 = 6^2$

Solve for x. Simplify:

$x^2 + (x^2 + 4x + 4) = 36$

Simplify:

$2x^2 + 4x + 4 = 36$

Subtract:

$2x^2 + 4x - 32 =0$

Divide:

$x^2 + 2x - 16 = 0$

The equation is not factorable, so we can consider using the quadratic formula:

$\displaystyle x = \frac{-b\pm\sqrt{b^2 -4ac}}{2a}$

In this case, a = 1, b = 2, and c = -16. Substitute:

$\displaystyle x= \frac{-(2)\pm\sqrt{(2)^2-4(1)(-16)}}{2(1)}$

And evaluate:

$\displaystyle \begin{aligned}x &= \frac{-2\pm\sqrt{68}}{2} \\ \\ &= \frac{-2\pm\sqrt{4\cdot 17}}{2} \\ \\ &= \frac{-2\pm2\sqrt{17}}{2} \\ \\ &= -1 \pm \sqrt{17} \end{aligned}$

Hence, our two solutions are:

$\displaystyle x = -1 + \sqrt{17} \approx 3.1\text{ or } x = -1 - \sqrt{17} \approx -5.1$

Lengths cannot be negative, so we can ignore the second solution.

Hence, the value of x or the first side length is about 3.1 centimeters.

Since the other side length is two centimeters longer, the other side is about 5.1 centimeters.

In conclusion, the two legs of the right triangle are approximately 3.1 cm and 5.1 cm and the hypotenuse is 6 cm.

Kendall has three jars of golf balls. One jar has a white and pink golf ball. The second jar has an orange and purple golf ball.

Mila [183]

Answer:

<h2>The total number of outcomes is 8.</h2>

Step-by-step explanation:

We know that there are different golf balls, white and pink, orange and purple, yellow and red. There are three jars with two golf balls each.

If Kendall chooses one golf ball from each jar, the total number of balls selected would be 4. Now, there are two different colors per jar, and 8 total golf balls with different colors. But, the sets can't have repetitions, and the order matters.

Having said that, the total number of possible sets is:

White, Orange, Yellow.
White, Purple, Red.
White, Orange Red.
White, Purple, Yellow.
Pink, Orange, Yellow.
Pink, Purple, Red.
Pink, Purple, Yellow.
Pink, Orange, Red.

Notice that these eight outcomes includes all possible results.

Therefore, there are 8 possible outcomes.
