Answer:
Option C is correct
76 feet
Step-by-step explanation:
Area of square(A) is given by:

where, s is the side of the square.
As per the statement:
A square ceiling has an area of 360 square feet.
⇒A = 360 square feet.
then;

⇒
Perimeter(P) of square is given by:

then;

Therefore, 76 feet molding does he need.
Answer:
The answer is "
"
Step-by-step explanation:
A = area of the pigpen
x = its perpendicular length of the sides of the stone wall
Maximize function:

So, the size of pigpen is = 100 ft by 200 ft that is (perpendicular and parallel to wall), that's why the answer is "
"
Answer:
2x − 9 and x + 6
Step-by-step explanation:
2x² + 3x − 54
Factor using the AC method.
2 × -54 = -108
Factors of -108 that add up to 3 are +12 and -9.
Divide by 2 and reduce: 12/2 = 6/1, -9/2 = -9/2.
Therefore, the factors are x + 6 and 2x − 9.
Here are a few doubles facts:
5+5=10
2+2=4
3+3=6
A double is simply a pair of identical numbers added together. There's a pair of doubles you can <em>subtract </em>1 from to get 6+7, and there's a pair you can <em>add</em> 1 to get the same answer. What are those pairs?
Hint: If you take the example 3+4, you can either <em>subtract 1</em> from the double 4+4 or <em>add 1</em> to the double 3+3 to obtain your answer.
