Answer:
n = 1
Step-by-step explanation:
Add 20 to both sides, obtaining
n = 4 - 3n
Next, add 3n to both sides:
4n = 4
Finally, solve for n by dividing both sides by 4:
n = 1
Slot method or permutations
top 3
6 for first slot
5 for 2nd slot
4 for 3rd
6*5*4=120
120 possiblites
answer is C
I don't think the numbers exist. 6 and 2 don't work because 6 * 2 does not equal 8. If you were solving a quadratic equation by factoring and you needed to find the two numbers, and you can't find them, you can solve the quadratic equation by using the quadratic formula.
Answer:
32
Step-by-step explanation:
4 × 8 - 32
Hence, 32 is the required answer.
Answer
4800 ft3
Step-by-step explanation:
Formula for volume of a pyramid is 1/3*base*hight
because you do 20*20=400ft2 for the base
Then you times 36 (the hight) by 1/3 and get 12
Then you do 400*12=4800ft3 theres your answer
hope this helps
