Answer:

Area = 21 un²

Explanation down Below!

Step-by-step explanation:

You don't need to worry about the 8 at all at this point

To find the area of a parallelogram you need to do base x height.

The height is 7, and the base of that height is 3.

7 x 3 = 21

Let me tell you why you do base x height.

if you cut out the triangle from the top and place it at the bottom it will become a rectangle.

The formula for a rectangle is base x height so this is why the formula works.

There is a picture for your reference.

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Can someone help me? find the solution for this system of equation ​
puteri [66]

Answer:

(5/6, 8/5)

Step-by-step explanation:

We multiply the second equation by 2, and then add the equations together.

12x+15y=34

-12x+10y=6

------------------

25y=40

We divide by 25 on both sides, and get that y = 8/5. We substitute y into either of the equations.

-6x +5(8/5)=3

Do the multiplication.

-6x+8=3

Subtract 8 from both sides.

-6x=-5

Divide by -6 on both sides.

x=5/6.

What are the coefficients of x in the following terms?<br>I don't understand coefficients.<br><br>​
solmaris [256]

Answer:

  27. 3

  28. 2a

  29. y²

  30. 280yz

  31. 1

  32. 1/3

Step-by-step explanation:

One way to think about a coefficient is this: Set the value of the variable of interest to 1 and evaluate the expression. The value of the expression is the coefficient of the variable of interest.

Here, you're only interested in the variable x, so its coefficient is everything that is not x. The coefficients are ...

27. 3

28. 2a

29. y²

30. 280yz

31. 1 . . . . . a lot of students get tripped up by this one. Setting x=1 makes it obvious.

32. 1/3

_____

Sometimes you're asked for the coefficient in a <em>term</em>. In the case of the term 280xyz, the appropriate answer to that question is 280, <em>the constant that multiplies all the variables</em>. When no constant is showing, the coefficient is 1, as in question 31.
