Answer:
Since the formula is (1/2) base height, (1/2) of 10 is 5 so multiply 5 times the base polynomial resulting in 20x^2y + 10xy^2 ft^2. So, if you multiply the length times width then divide by 2 you get the same answer. Sorry if this is incorrect.
Hope this helps, have a great day and stay safe!
Answer:

Answer:
5+4x=-11
Step-by-step explanation: First it says "The sum of 5 and four times a number" which going to be 5+4x because 4 time a number so it's going to be 4x. Then the last thing you will need to do is to add in the equal sign which the whole equation going to be 5 + 4x = -11.
Let ,Cynthia invested $x
Rate = 5%per year
time = 3 year
Amount
A= P(1+r/100)^t
8000=x(1+5/100)^3
8000=x(21/20)^3
x= (8000x8000)/9261
x=6910.7$
Therefore she can invest =$6910.7 =5322.14 pound
