Try grouping in paires
4x^3 + 28x^2 + 7x + 49
= 4x^2(x + 7) + 7(x + 7) - note that (x + 7) is common to the 2 parts, so
= (4x^2 + 7)(x + 7)
Answer:
One Way Trip There = ($460.22)
There and Back Trip = ($465.26)
Answer:
38 pages per hour
Step-by-step explanation:
Rate of reading = 
By substituting the given values in the question,
Total number of pages read by Davida = 
= 
Time taken by Davida = 45 minutes
Since, 1 minute = 
hours
Therefore, 45 minutes = 
hours
Rate of reading = 
= 
= 38 pages per hour
Therefore, rate of reading by Davida is 38 pages per hour.
Answer:
y^2+xy+x+3y+2
Step-by-step explanation:
first of all we have to multiplies the y in the second bracket for all numbers in the first bracket.
so we have:
xy+y^2+2y
now we have to do the same with 1
x+y+2
now we have to unite the two solutions
xy+y^2+2y+x+y+2
at least we have to added up the similar terms (that have the same literal part)
y^2+xy+x+3y+2
Answer:
-12
Step-by-step explanation:
r = -3
4/9 * (-3) = -4/3
-4/3 * (-3) = 4
so, 4 * (-3) = -12
