Answer:

Yes

Step-by-step explanation:

The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.

Answer:

(sqrt(x) +1)(sqrt(x)-2)

Step-by-step explanation:

$x - 2 \sqrt{x} + \sqrt{x} - 2 \\ \sqrt{x} ( \sqrt{x} - 2) + 1( \sqrt{x} - 2 ) \\ ( \sqrt{x} + 1)( \sqrt{x} - 2)$

The measures of a pair of consecutive angles of a parallelogram have the ratio 5:7. Find the measure of each angle of the parall

Margaret [11]

5 : 7 = 5x : 7x

Sum of a pair of consecutive angles of a parallelogram = 180⁰.

5x+7x=180
12x = 180
x= 15

5x=15*5 = 75⁰
7x=15*7 = 105⁰

Two angles are 75⁰ each,
and 2 angles 105⁰ each.

Check:
Sum of angles in the parallelogram is 360⁰.
75*2 + 105*2 = 360
360 = 360 True
