Answer:
-12
Step-by-step explanation:
4 time 3 is 12
since he owes her its negative, so it is -12
Answer is B$31 is the cost per day to rent the car and $0.18 is the cost per mile<span />
The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is
A = 0.5bh
The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:
4A = 33
Substituting A = 0.5*5.5*h = 2.75h to the equation:
4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet
Answer:
You would need 64 pounds.
STEP BY STEP EXPLANATION:
4 pounds covers 434 sq ft
434 goes into 6944, 16 times
16 x 4 = 64
I hope this helps :)
Have a nice day!
You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
