Answer: A fraction is in lowest terms when the numerator and denominator have no common factor other than 1.
Step-by-step explanation: The factors of 2 are 1 and 2. The factors of 4 are 1, 2, and 4. 2 and 4 share a common factor: 2.
65+55=120
120÷2=60
So, it take them 60mins if they worked together.
Answer:
y = 2 ( x + 3 ) 2 − 4
Step-by-step explanation:
Use the form a x 2 + b x + c , to find the values of a , b , and c . a = 2 , b = 12 , c = 14 Consider the vertex form of a parabola. a ( x + d ) 2 + e Substitute the values of a and b into the formula d = b 2 a . d = 12 2 ( 2 ) Simplify the right side. d = 3 Find the value of e using the formula e = c − b 2 4 a . e = − 4 Substitute the values of a , d , and e into the vertex form a ( x + d ) 2 + e . 2 ( x + 3 ) 2 − 4 Set y equal to the new right side. y = 2 ( x + 3 ) 2 − 4
