Answer:

3. C

4. A

4. D

Step-by-step explanation:

When adding two fractions, you must add them with the same denominator. This means finding the lowest common multiple of 10 and 5, which is 50. Simply multiply each fraction by the denominator of the opposite fraction:

$\frac{4}{5} * 10 = \frac{40}{50}$

$\frac{9}{10} * 5 = \frac{45}{50}$

Add the two fractions together:

$\frac{40}{50} + \frac{45}{50} = \frac{85}{50} = 1 \frac{35}{50} = 1 \frac{7}{10}$

7 + 1 + 1 + 7/10 = 9 7/10

Again, make the denominator the same number by multiplying the fraction by the denominator of the other fraction:

$\frac{3}{4} * 3 = \frac{9}{12}$

$\frac{1}{3} * 4 = \frac{4}{12}$

9/12 + 4/12 = 13/12 = 1 1/12

10 + 15 + 1 + 1/12 = 26 1/12

Again, multiply the fraction by the denominator of the opposite fraction:

$\frac{1}{2} * 3 = \frac{3}{6}$

$\frac{1}{3} * 2 = \frac{2}{6}$

3/6 + 2/6 = 5/5

7 + 6 + 4 + 5/6 = 17 5/6

Which is the best definition of a square? A. a 4-sided polygon with all sides equal B. a parallelogram with all sides equal and

Veronika [31]

I would say B) A parallelogram with all sides equal and all angles equal. Parallelograms aren't all squares. They can be rectangles and rhombuses. I would say B. They all have the same lengths on all sides. They all have the same angles as well. Take a look at the pictures below. They are all parallelograms. All sides are the same, and all angles are the same.
