Answer:
Factor x^2−8x−48 using the AC method.
(x−2) (x+4)
Just switch the x and the 3
Answer:
x = -4
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis

First, divide 3 from both sides of the equation:
(3(-3 - 3x))/3 = (27)/3
-3x - 3 = 27/3
-3x - 3 = 9
Next, isolate the variable, x. Note that what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.
First, add 3 to both sides:
-3x - 3 (+3) = 9 (+3)
-3x = 9 + 3
-3x = 12
Next, divide -3 from both sides:
(-3x)/-3 = (12)/-3
x = 12/-3
x = -4
x = -4 is your answer.

Answer: No the banner is not square.
Step-by-step explanation:
If it were square, the diagonal would be about 35.36 inches.
Pythagorean Theorem: a² + b² + = c²
?25² + 25² = 48² ?
625 + 625 ?=? 2304
1250 ≠ 2304
√1250 ≈ 35.3553
