serious [3.7K]

Answer:

Square

Step-by-step explanation:

If its 4 sided and two measures are 90 degrees then that means the other two must be 90 degrees. That means its a square or a rectangle. Now since the 4 sides arent all the same and two sides being 6 and two sides being 5, you can rule out it being a square.

What is the simplified form of the quantity of x plus 9, all over 5 − the quantity of x plus 5, all over 5?

ANEK [815]

Answer:

the quantity of 4 over 5

Step-by-step explanation:

According to the description, we have the quantity $\frac{x+9}{5} -\frac{x+5}{5}$

Since both fractions have the same denominator (5), we just need to subtract the numerators:

$\frac{x+9}{5} -\frac{x+5}{5}=\frac{x+9-(x+5)}{5} =\frac{x+9-x-5}{5} =\frac{4}{5}$

Now we know that the simplified form of the expression is $\frac{4}{5}$ ; translating that fraction into words we get: the quantity of 4 over 5

We can conclude that the simplified form of the quantity of x plus 9, all over 5 − the quantity of x plus 5, all over 5 is the quantity of 4 over 5
