Part 1: 2×2×3×3×3=108 (c)
Part 2: 10×9×26×25×4=234000 (c)
Part 3: 10×9×8×7×6×5×4×3×2×1÷(3×2×1)=604800 (d)
Part 4: 11C4=11×10×9×8÷(4×3×2×1)=330 (a)
Part 5: ⅕=20% (c)
Part 6: 100-2.9=97.1 (d)
Your answer is 3277 because a negative divided by a negitive makes it a positive.
Answer:4(2x + 1) = 12x + 3 - 4x +1=0
Step-by-step explanation:
group like terms =4(2x+1)=12x-4x+3+1
add similar elements=4(2x+1)=8x+3+1
add the numbers=4(2x+1)=8x+4
expand=8x+4=8x+4
subtract 4 from both sides 8x+4-4=8x+4-4
simplify=8x=8x
subtract 8x both sides=0
Answer: 3 units
Step-by-step explanation:
the volume of a cone C = πr²h/3
C = 18π, h =2x, r = diameter/2 = 2x/2 =x
18π = π* x²* 2x/3
divide through by π
18 = x² * 2x/3
multiply through by 3
54 = 2x³
divide through by 2
27 = x³
x =∛27 = 3
x = 3 units = radius
