Answer:

  • rectangle: 11 × 20
  • triangle area: 110 u²
  • parallelogram area: 110 u²

Step-by-step explanation:

See below for a graph showing the parallelogram and the rectangle.

The dimensions of the rectangle are 11 by 20. The rectangle area is ...

  rectangle area = bh = (11)(20) = 220 . . . square units

There are 2 right triangles with a base of 10 and a height of 1. There are 2 right triangles with a base of 10 and a height of 10. The total area of the triangles is ...

  triangle area = 2(1/2)(10)(1) +2(1/2)(10)(10) = 10(1 +10) = 110 . . . square units

The area of the parallelogram is the difference of these, ...

  parallelogram area = rectangle area - triangle area

  = (220 units²) -(110 units²) = 110 units²

The area of parallelogram ABCD is 110 square units.

_____

<em>Check</em>

The parallelogram has a base of 10√2 and a height of 5.5√2, so an area of (10√2)(5.5√2) = 110 square units. This matches the above result.

In step 2, how do you know that 5x? and -12x? are like terms? If you could please help me with 1,2,3 if not just 2
klemol [59]
First we need to define what a like term is:

Like term meaning:

Terms whose variables (such as x or y) with any exponents (such as the 2 in x2) are the same. Examples: 7x and 2x are like terms because they are both "x".

Answer (for question 1):
For step one, you would just have to expand the brackets. The number of times multiplication would be used is 3 times. If you are confused, I attached a diagram in my ‘side notes’ section.

Answer (for question 2):
-5x squared and -12x squared are like terms because they both end in x squared.

Answer (for question 3):
There are no more like-terms.

Hope this helps!

Which number line shows the solution to the inequality –2(3x – 1) &lt; 8? A. Number lines from minus five to five by increament
never [62]

Answer:

The correct option is B.

Step-by-step explanation:

The inequality is: -2(3x - 1) < 8.

Solve for <em>x</em> as follows:

-2(3x - 1) < 8

-6x + 2 < 8

-6x < 6

-x < 1

x > -1

The solution for <em>x</em> is in the interval (-1, ∞].

The number line will be:

B. Number lines from minus five by increment of one from left to right and each tick mark is labeled. Shaded part from open circle at minus one to infinity

mario62 [17]

Answer:

3w² = 243

Step-by-step explanation:

Width = w

Length = 3w

Area = 243 square units
