Answer:

FGI and HIJ,EGH and HIJ, and EGH and EFG

Step-by-step explanation:

To answer this, you must find if the planes share a common side

just go down the list and you will see that all of them except HIJ and EFG share a common side so they intersect

Which expressions are equivalent when y = 2 and y = 5? 2 y minus 1 and 3 y minus 5 + y 5 y + 4 and 7 y + 4 minus 2 y y + 7 and y

noname [10]

Answer:

Option b

Explanation:

The question is shown in the attached image

To answer this question, we will simply substitute in the given expressions with the values y=2 and y=5

The correct option will be the one having equal vales in both cases

1. Option a:

At y = 2:

2y - 1 = 2(2) - 1 = 3

3y - 5 + y = 3(2) - 5 + 2 = 3

At y = 5:

2y - 1 = 2(5) - 1 = 10

3y - 5 + y = 3(5) - 5 + 5 = 15

This option is incorrect, since both expressions are not equal at y = 5

2. Option b:

At y = 2:

5y + 4 = 5(2) + 4 = 14

7y + 4 - 2y = 7(2) + 4 - 2(2) = 14

At y = 5:

5y + 4 = 5(5) + 4 = 29

7y + 4 - 2y = 7(5) + 4 - 2(5) = 29

This option is correct, since both expressions are equal at the two vales of y

3. Option c:

At y = 2:

y + 7 = 2 + 7 = 9

y + 2 + y = 2 + 2 + 2 = 6

At y = 5:

y + 7 = 5 + 7 = 12

y + 2 + y = 5 + 2 + 2 = 12

This option is incorrect, since both expressions are not equal at y = 2

4. Option d:

At y = 2:

3y - 4 = 3(2) - 4 = 2

3y - 2 + y = 3(2) - 2 + 2 = 6

At y = 5:

3y - 4 = 3(5) - 4 = 11

3y - 2 + y = 3(5) - 2 + 5 = 18

This option is incorrect, since both expressions are neither equal at y = 2 or y = 5

Hope this helps :)

A quadrilateral has all sides congruent, opposite sides are parallel, and opposite angles are congruent.

VashaNatasha [74]

Answer:

B: A square

Step-by-step explanation:

Let's use the process of elimination:

We know that each shape here has opposite parallel sides so there's not much we can do about that one.

All sides congruent automatically gets rid of A.) Rectangle and C.) Parallelogram because they do not always have congruent sides

Opposite angles are congruent gets rid of D.) Rhombus. Although a rhombus can have all congruent angles, it isn't always congruent the way a square is. The definition of a rhombus is a quadrilateral with equal side lengths. Not angles.

So the only shape that meets each criteria all the time is a square.
