Answer:

4. A rectangle is a square

Step-by-step explanation:

A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.

How do I figurevout <br> 2(x-y) and 2x-2y

Umnica [9.8K]

Answer:

2(x-y) and 2x-2y are equivalent.

Step-by-step explanation:

To figure out 2(x-y) and 2x-2y, you can apply the distributive property on

$2(x - y)$

to get:

$2(x - y) = 2x - 2y$

Or we can factor

$2x - 2y$

to get:

$2x - 2y = 2(x - y)$

This implies that, the two expressions are equivalent.

Which statement about this product is true? 0.36×(-7 5/8)

Schach [20]

A.It is less than -7 5/8
because multiplying by a number less than 1
gives a smaller number.
B.It is greater than -4
because 0.36×(7 5/8)
0.36*(7 5/8) is less than 1/2 * 8
C.It equals -7 5/8
because 36/36
equals 1
, and 1
times any number equals that number.
D.It equals 0
because 0.36
rounded to the nearest whole number is 0
, and 0
times any number is 0.
THESE ARE ALL THE ANSWER CHOICES!!!

Add 7/8 + 2 3/24 + 6 1/6

natali 33 [55]

Answer:

9 4/24 or 9 1/6

Find the LCM(lowest common multiple) of 8, 24 and 6.
The LCM of 8, 24 and 6 is 24.
We now want to turn all the denominators into 24 so we are going multiply 7/8 by 3 and 1/6 by 4. We won't need to turn the denominator of 3/24 into 24 because it's already 24
Whatever you do to the denominator you have to do to the numerator, so you also have to multiply the numerator of 7/8 by 3 and the numerator of 1/6 by 4
That now results in 21/8 + 2 3/24 + 6 4/24
Now you have to add all the fractions together which is going to equal to 28/24
Because 28/24 is more than the whole, subtract 28 from 24 which gives us 4. That 4 is now our new numerator
We are now going to all the whole numbers 6+2+1=9. Incase you're wondering, the '1' came from the 28/24
The answer you should get should be 9 4/24 or if it should be simplified it would be 9 1/6
