To solve this problem you must apply the proccedure shown below:

1. By definition, the opposite sides of a parallelogram are parallel and have equal length.

2. The figure attached shows that the opposite sides with equal length are:

$a=c\\b=d$

3. Keeping this on mind, you have that the side c and a are equal and measure six centimeters.

4. To find the length of the other sides, you must apply the following formula for calculate the perimeter of a parallelogram:

$P=2(a+b)$

4. If you solve for b, you will obtain the measure of b and d:

$30cm=2(6cm+b)\\30cm=12cm+2b\\b=9cm$

Therefore the answer is:

The lengths of the sides are: 6 cm, 6 cm, 9 cm and 9 cm.

You are selling lemonade for $1.50, a bag of kettle corn for $3, and a hot dog for $2.50 at a fair. Write and simplify and expre

denpristay [2]

You are selling the following items.
=> lemonade = $1.50
=> kettle corn = $3
=> hotdog = $2.50
=> p = number of people

Now, we need to write the expression of this given equation:
=> Amount = p(1.50 + 3 + 2.50) or Amount = p(1.50) + p(3) + p (2.50)
In where p is the number of people who will buy your food and will be multiplied to the amount of each food you’re selling to be able to get the total amount of money you will have.

Part A: Factor x2y2 + 6xy2 + 8y2. Show your work. (4 points) Part B: Factor x2 + 8x + 16. Show your work. (3 points) Part C: Fac

skad [1K]

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

An ant crawls at a rate of 2 1/6 ft per minute. At this rate, how long does it take the ant to crawl a distance of 5 1/5 ft? Ent

tangare [24]

For 2 1/6 = 13/6 Ft, ant takes = 1 min.
So, for 1 ft, it takes = 6/13 min.

Now, for 5 1/5 = 26/5 min. it would take = 6/13 * 26/512/5 = 2.4 min

In short, Your Answer would be 2.4 min

Hope this helps!

PLS ANSWER QUICK LOL

Setler [38]

(3j, 3k) and (3/j, 3k)

So if their x values have the same signs and their y values have the same signs, they are in the same quadrant.

If j is negative, both 3j and 3/j would be negative. If j is positive then both 3j and 3/j are positive.

And 3k is the same as 3k.
