Answer:
2 should be distributed as 2y + 16; y = 8
Step-by-step explanation:
We have to distribute 2, then:
Now we have to sum (-2y) in both sides of the equation:
Finally we have to divide both sides of the equation in 2:
Then the answer is 2 should be distributed as 2y + 16; y = 8
Hope this helps.
Answer:
Step-by-step explanation:
you can figure out the area by using two formulas: area of a circle (on each end are two semi circles which when combined, make a circle) and area of a rectangle
Acircle: pi(r^2) = pi(5^2) = 25pi
Arectangle: length*width = 20*10 = 200ft^2
area of composite figure: (25pi ft^2) + 200ft^2
Answer:
g-21
Step-by-step explanation:
First you would want to add all of the hours traveled already. Since g would be the total amount of house that Greg would need to drive to get to his destination you would subtract the amount of hours traveled from g. 8+9+4=21, 21 hours traveled already. The expression would be g-21.
