Answer:
4t+6
Step-by-step explanation:
To find the perimeter of the rectangle you add the length of the sides.
Perimeter= t+ t+ t+ 3+ t+ 3= <u>4t+6</u>
or
Perimeter=2(t)+ 2(t+3)= 2t+ 2t+ 6= <u>4t+6</u>
Answer:
(5 + 3y)(25 - 15y + 9y²)
Step-by-step explanation:
This is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
125 + 27y³
= 5³ + (3y)³ with a = 5 and b = 3y
= (5 + 3y)(5² - 5(3y) + (3y)² )
= (5 + 3y)(25 - 15y + 9y²)
Answer:
If you gave out 4 cookie to 
people you would have 5 cookies leftover, but if you gave out 12 cookie to people you would need 11 more cookies.
600,000,000+ 70,000,000+ 200,000+ 600+ 40
You could easily change the 2 1/2 to a 2.5 and do 2.5-6=-3.5
