Answer:
4u^2 + 16u + 15
Step-by-step explanation:
Multiply each of the terms in the first binomial by each of the terms of the second binomial (4 multiplications in all).
(2u + 3)(2u + 5) = (2u)(2u + 5) + 3(2u + 5)
= (2u)(2u) + (2u)(5) + 3(2u) + 3(5)
= 4u^2 + 10u + 6u + 15
= 4u^2 + 16u + 15
Answer: 68°F
Step-by-step explanation:
To find the range for a set of numbers that are given, we subtract the lowest number from the biggest number. In this case, we subtract the lowest temperature from the highest temperature. This will be:
= 49°F - (-19°F)
= 49°F + 19°F
= 68°F
