What are the lengths of line segments AB and BC?

Mathematics

Natalka [10]3 years ago

Answer:

AB = 10 and BC = 28

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, thus

AB = DC, that is

3y - 2 = y + 6 ( subtract y from both sides )

2y - 2 = 6 ( add 2 to both sides )

2y = 8 ( divide both sides by 2 )

y = 4

Hence AB = 3y - 2 = (3 × 4) - 2 = 12 - 2 = 10

And

AD = BC, that is

2x - 4 = x + 12 ( subtract x from both sides )

x - 4 = 12 ( add 4 to both sides )

x = 16

Hence BC = x + 12 = 16 + 12 = 28

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be​
Norma-Jean [14]

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Hope this helpes!

A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could represe
Mrac [35]

Answer:

B. y= -x^2+50x-300

Step-by-step explanation:

A. y^2=4x^2-100

B. y= -x^2+50x-300

C. x=-y^2-400

D. x^2=-6y^2+200

we are to find profits (y) when the company sells x items

Option A can be used to calculate the profit (y) squared

Option B can be used to calculate profits (y)

Option C can be used to calculate items sold(x)

Option D can be used to calculate items sold squared(x^2)

We are asked to find the weekly profit (y) function which eliminate options A, C and D leaving us with option B

Therefore, the weekly profits (y) function in thousands of dollars when the company sells x items is

B. y= -x^2+50x-300
