Step-by-step explanation:
Answer:
The answer is x=9 and/or x = -12
Step-by-step explanation:
This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.

which simplifies to -3 add or subtract the sqrt of 441 divided by two.
Answer:
C
Step-by-step explanation:
y = 2x + 5
the slope (m) of this line is 2 (which can be written as 2/1)
The slope of a perpendicular line is -1/m (the reciprocal of the slope with the opposite sign)
so m = 2/1 => -1/m = - 1/2 = the slope of a line perpendicular to y = 2x + 5
Answer: A:3 rolls B: $38.67
Step-by-step explanation:
1. Convert all units to the same value (feet to inches, as the opposite gives fractions)
2. Use new equation and multiply the said new variable (84*3 & 96*3)
3. The new total should amount to the total area (540)
4. Divide found area by 12 to convert back into feet (45)
5. Divide the feet by feet per roll (3)
6. Multiply for Cost
Answer:
7 is a obtuse and 2 is acute
