The answer is "Study 2"
Step-by-step explanation:
In Study 2:

For the second question I got $2.34
<span>Answer: Yes, the 3 foot 3 foot square opening in your ceiling is big enough to insert a 4x8 piece of plywood.</span>
<span>In a 3x3 foot square, we can form two right triangles with same diagonal side or hypotenuse. .</span>
Using the Pythagorean theorem/formula, we can find the length of the hypotenuse or the longest side of the triangle ( c) given the two sides a and b
Substitute values a=3 and b=3 to formula
a^2^+b^2^=C^2^=
3^2^+3^2^=C^2^=
9+9= C^2^
C= square root of 18
C=4.24
<span>A 4x8 piece of plywood can be inserted in a 4.24 opening diagonally.</span>
Factorial is the correct answer because in combinations the order does not matter
Answer:
2 and -10
Step-by-step explanation:
let the two integers be x and y.
so, x+y=-8---‐-------(1)
and,
x=y+12-------‐-----(2)
from (1) and (2),
(y+12)+y=-8
or, 2y=-8-12
or, y=-20/2
or, y=-10
substitutting the value of y in (2),
x=-10+12=2
therefore the required integers are 2 and -10.
