-n\2 + 9n + 4 is the answer
First one is 3
Second one is 6
Approx. 3 1/3 cups. 1 1/2 dozen equals 18 cookies. 90/18=5 . Then you multiply 5 by .666(rep) and it equals =3.3333333(rep) or approx. 3 1/3 cups of sugar.
The answer is A). 5*4=20 one fifth is 4.
Answer:
The diagonal is 421.
Step-by-step explanation:
This is a difficult question. To find the diagonal, you need to find the base and the height of the square. After that, you need to make it a triangle, by using this equation;
(A being area, B being base, and H being height) then find the length of the hypotenuse of the triangle, which I will do for you.
The B and H = 416. Plug it into the equation now;
Now that you have done that, we know that the area of our new triangle is 86,528.
The diagonal is:
