Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.
If you divide 288 divided 48 which is 6
so you'll need 6 cups of sugar
Answer:
I think its 5%
12/240=0.05
0.05=5%
Sorry if its wrong I haven't studied about percentages yet in school
Answer:
See below
Step-by-step explanation:
<u>Given</u>
- f(x)=2x + 5 and
- g(x)=x^2 - 3
=================
<u>f(3)</u>
<u>g(2)</u>
<u>g(f(-1))= 6</u>
<u>f(g(-1))= 1</u>
<u>g(f(x))</u>
- g(f(x))= (2x +5)^2 - 3 = 4x^2 + 20x + 25 - 3 = 4x^2 + 20x + 22
