Expression for the quotient of b divided by the difference of two minus 3
uysha [10]

Answer:

The required expression is

                                     \frac{b}{2 - 3}  = - b

Step-by-step explanation:

 

Difference of two minus three = 2-3

Quotient of b divided by the difference of two minus three is

                                             \frac{b}{2-3} = \frac{b}{-1} = - b

Therefore, the required expression is

                                                  \frac{b}{2-3}  \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \  - b

We have a right triangle that has am 8 meter and 21 meter leg .Find the hypotenuse
Serjik [45]

Answer:

hypotenuse is 22.47 m

Step-by-step explanation:

The length of both legs of a right angle triangle are 8m and 21 m

We need to find the hypotenuse

To find hypotenuse we use Pythagorean theorem

Hypotenuse is AC  and other two legs are AB  and BC

AC^2 = AB^2 + BC^2

Hypotenuse ^2 = 8^2 + 21^2

hypotenuse = \sqrt{8^2 + 21^2}

= \sqrt{64 + 441}

= \sqrt{505}

= 22.47

So the length of the hypotenuse is 22.47 m
