A. Yes, since a square is a type of rectangle, but it has four congruent and parallel side.
B. Yes, since a square is also a type of parallelogram. Therefore it has 2 pairs of parallel sides.
C. No, they have 2 pairs of congruent sides.
Hope this helps :D

Part A: Yes, because a square is both a rectangle and a rhombus so therefore it is.
Part B:Yes, Because square falls under parallelogram and a parallelogram has 2 parallel sides.
Hope it helped✨

Marco thinks the total number of runs a team scores in a season is a better indicator of how many wins it will have in that seas
FrozenT [24]
This is a fair assumption, but not true in every instance. Since home runs do not indicate how many runs score, which are the decider in a win or a loss, they are less accurate at predicting.

Weights of different sandwiches in two lengths are shown in the table.
Alexandra [31]

Answer:

Egg salad sandwich is proportional to its length

Step-by-step explanation:

Weight of Sandwiches by Length of Roll

                                        6-inch Roll      12-Inch Roll

Cheese sandwich               \frac{1}{4}                      \frac{3}{4}

Chicken salad sandwich     \frac{3}{4}                     1\frac{3}{4}

Egg salad sandwich            \frac{2}{3}                   1\frac{1}{3}

For cheese sandwich proportion

\frac{6}{\frac{1}{4}}=\frac{12}{\frac{3}{4}}\\24 \neq 16

So, Cheese sandwich weight is not proportional to its length

For Chicken salad sandwich proportion

\frac{6}{\frac{3}{4}}=\frac{12}{\frac{7}{4}}\\8 \neq \frac{48}{7}

So, chicken salad sandwich is not proportional to its length

For Egg salad sandwich  proportion

\frac{6}{\frac{2}{3}}=\frac{12}{\frac{4}{3}}\\9=9

So, egg salad sandwich is proportional to its length

Which angles are a linear pair
mihalych1998 [28]

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

which expression represents purely real numbers and which expression represents non-real complex number?​
Lyrx [107]

Answer:

Step-by-step explanation:

Complex numbers are the numbers represented by the expression = a + bi

Here a = real part of the number

bi = imaginary part

a and b are the real numbers.

i^9=(i^2)^4.(i)

    =(-1)^{4}.i [Since, i^2=-1]

    =i

Therefore, its a non real complex number.

2 - \sqrt{-49} = 2-\sqrt{(-1)(7)^2}

               = 2-7\sqrt{-1}

               = 2-7i

This number is a Non real complex number.

\sqrt{(-18)^2}=18\sqrt{-1}

              = 18i

It's a non real complex number.

3 + 2i

It's a non real complex number.

-289

It's a purely real number.

4-32i^2=4-32(-1)

             = 4 + 32

             = 36

It's a purely real number.
