16 popcorn balls  1st layer                             16+12+8+4 = 40 popcorn balls in the
12 popcorn balls 2nd layer                                         stack.
8 popcorn balls 3rd layer
4 popcorn balls 4th layer

Hi! So if we lay out 16 popcorn balls, and each time we take away four, this is what would happen gradually,

16 bottom + 12 1st layer + 8 2nd layer + 4 3rd layer

16+12+8+4 = 40 popcorn balls!

HELP PLEASE I NEED ANSWER ASAP!

Answer:

86+18\sqrt{2}

Step-by-step explanation:

Use the properties of 45-45-90 triangles to get a side length of 18 for the 2 legs of the isosceles triangle. Then add 43+18, which is the shorter length of the rectangle, +25, which is the longer edge, +18\sqrt{2}. The answer is now 86+18\sqrt{2}.

Solve for n -3n-5=16
Nezavi [6.7K]

Answer:

n = -7

Step-by-step explanation:

Solve for n:

-3 n - 5 = 16

Hint: | Isolate terms with n to the left-hand side.

Add 5 to both sides:

(5 - 5) - 3 n = 5 + 16

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

-3 n = 16 + 5

Hint: | Evaluate 16 + 5.

16 + 5 = 21:

-3 n = 21

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 21 by -3:

(-3 n)/(-3) = 21/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 21/(-3)

Hint: | Reduce 21/(-3) to lowest terms. Start by finding the GCD of 21 and -3.

The gcd of 21 and -3 is 3, so 21/(-3) = (3×7)/(3 (-1)) = 3/3×7/(-1) = 7/(-1):

n = 7/(-1)

Hint: | Simplify the sign of 7/(-1).

Multiply numerator and denominator of 7/(-1) by -1:

Answer: n = -7
