Answer:

1, 3, 4

Step-by-step explanation:

Among these answer choices, you're looking for two expressions separated by a minus sign. Choice 2 is only one expression, so does not meet the required criterion.

1. 6(x+7)-2

3. 4f-2g

4. 3xyz-10

Which expression is equivalent to 2(3x + 4y + x)?

Elena L [17]

$\huge\textsf{Hey there!}$

$\large\text{2(3x + 4y + x)}$

$\large\textsf{DISTRIBUTE 2 WITHIN the PARENTHESES}$

$\large\text{2(3x) + 2(4y) + 2(x)}$

$\large\text{2(3x) = \boxed{\bf 6x }}$

$\large\text{6x + 2(4y) + 2(x)}$

$\large\text{2(4y) = \boxed{\bf 8y}}$

$\large\text{6x + 8y + 2(x)}$

$\large\text{2(x) = \boxed{\bf 2x}}$

$\large\text{6x + 8y + 2x}$

$\large\textsf{COMBINE the LIKE TERMS}$

$\large\text{(6x + 2x) + (8y)}$

$\large\text{6x + 2x = \boxed{\bf 8x}}$

$\large\text{8x + 8y}$

$\boxed{\boxed{\large\text{Answer: \huge \bf 8x + 8y}}}\huge\checkmark$

Nady [450]

Step-by-step explanation:

1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.

2.Clearly it forms a triangle in the parallelogram with three known lengths of side.

3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.

Alana claims that not all 4-sided polygons with 2 pairs of equal sides are parallelograms. Is she correct. Please explain why

sergiy2304 [10]

Answer:

No, she is not correct

Step-by-step explanation:

Given: Alana claims that not all 4-sided polygons with 2 pairs of equal sides are parallelograms

To check: whether she is correct or not.

Solution:

Any two-dimensional figure formed using straight lines is known as a polygon. Triangles, quadrilaterals are examples of polygons.

A parallelogram is a quadrilateral in which opposite sides are parallel.

Kite is a polygon made up of four sides with two pairs of equal sides that are adjacent to each other but it is not a parallelogram as its opposite sides are not parallel.

So, she is not correct.
