C. 48 inches
Add all the sides to find the perimeter
Answer:
Step-by-step explanation:
2x² + 5x - 12 = 0
- a = 2, b = 5, c = -12
- x = (-b ± D)/2a
- D = √b² - 4ac = √5² -4*2*(-12) = √25+96 = √121 = 11
- x = (-5 ± 11)/4
Correct choice is the second one or B
Answer:
35,000
Step-by-step explanation:
1. Find the difference between 75 and -51.
75 - (-51) = 75+51 = 126
2. Divide 126 by 3.6
126/3.6 = 35
3. Now what is the number 35? That is how much times the airplane has approached 1,000ft. So you have to multiply 35 and 1,000.
35 x 1,000 = 35,000.
4. Find the equation
([75 - x]/3.6) × 1,000, in which this case, x is the Fahrenheit the surroundings is in
a. Substitute x with -51.
b. The equation should follow the exact steps I mentioned earlier.

Answer:
okay so, i had a problem like this one and hated it, so ill try to help you out here
Step-by-step explanation:
If it is 81 all together it is safe to say the length and width is nine, making one mat six by 3, the little square being 3 by 3,
so the area of one mat would be six times three = 18
and if the width is 3, the length would be 6, unless it is cut in half, which we can assume it is not.
I hope this helps!
