Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
hope that helped!
Answer:
91 cm^2
Step-by-step explanation:
The bottom rectangle has an area of

A = 3 *7 = 21
Add the areas together
A = 70+21 = 91 cm^2
11/12 is less than one.
Two servings would be 1/2 + 1/2 pounds, so exactly one pound.
