Answer:
-2x³ - 2y² + z⁴
Step-by-step explanation:
Step 1: Write out expression
x³ - 2y² - 3x³ + z⁴
Step 2: Combine like terms (x³)
-2x³ - 2y² + z⁴
OK, like I explained in the last one KCF, (Keep Change Flip) so our problem is:
8/7÷5/8 So lets Keep 8/7 and change the divide sign to multiplication sign. and then for Flip you flip 5/8 to 8/5. So now our real problem is: 8/7*8/5= (8*8=64) and (7*5=35). So we have 64/35, now you just need to change this improper fraction to a proper one... message me if you have any trouble :)
Answer:
340
Step-by-step explanation:
Answer:
17.2 in
Step-by-step explanation:
The formula for arc length is s = rФ. Here we are to find r. Solving this formula for r, we get:
r = s/Ф
So, in this problem, r = (9 in) / (π/6) = 54/π in ≈ 17.2 in
It’s -1 the guy above me is right
