-2z^2+5z-5; Quadratic trinomial, 3 terms
Answer:
Area = 10 1/9 meters squared
Step-by-step explanation:
mixed number to improper fraction:
4 2/3 meters = 14/3 meters
2 1/6 meters = 13/6 meters
Area = length times width:
Area = (14/3) x (13/6)
= 182/18
Simplify fraction:
182/18 = 91/9
improper fraction to mixed number:
91/9 = 10 1/9 meters
AREA = 10 1/9 meters
Prime numbers below 30: 1, 3, 5, 7, 11, 13, 17, 19, 23, 29
2 prime numbers that sum up to 30:
1 and 29
7 and 23
13 and 17
The greatest possible product will be 13 x 17 = 221
Answer: The two prime numbers are 13 and 17
Answer:
The simplification for the expression is given as =( 7 + 2(a-3))/(a-3)
Step-by-step explanation:
To simplify the expression we will first convert the words to values in numbers and alphabets.
StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction
= 5/(a-3) -4/2 + 2/(a-3)
Having done that, let's move on and simplify the expression.
5/(a-3) -4/2 + 2/(a-3)
= 5/(a-3) -2+ 2/(a-3)
= 5/(a-3) + 2/(a-3) -2
= 7/(a-3) -2
=( 7 + 2(a-3))/(a-3)
