hey the answer is the last one z= 2k -5
Hey there :)
( 5y + 9 )( 6y - 1 )
We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms
First Outer Inner Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
30y² - 5y + 54y - 9
Combine, if any, the like-terms
30y² + 49y - 9
First you need to convert them to one common measurement... I'll use cm for the measurement.
- 1m = 100 cm
- 10 cm = 10 cm
- 50 mm = 0.1 cm
- 1 km = 100000 cm
Using this info to convert gives
The smallest is 50 mm which is equal to 5 cm
Less then -3...that would be -4
10 in, 24 in, and 26 in. By the Converse of the Pythagorean Theorem, the lengths must satisfy the equation c² = a² + b². Let 26 = hypotenuse and 10 and 24 the legs of the triangle.
26² = 10² + 24²
676 = 100 + 576
676 = 676.
Yes, they can be lengths of a right triangle.
