To simplify that question, you would normally say "20 is 80 percent of what number"
To find the answer you must grab the number 20 and divide it by 80% or 0.8
20 ÷ 80% = 25
20 ÷ 0.8 = 25

Answer:
1/2n+3=15
Step-by-step explanation:
the 1/2 is a fraction so 3 more than 1/2 times n is 1/2n+3=15
Answer:
The answer is
<h3>81x⁴ + 216x³ + 216x² + 94x + 16</h3>
Step-by-step explanation:
(3x + 2)⁴
<u>Using the Pascal's triangle</u>
For an exponent of 4 we have
( a + b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b³
Using a = 3x and b = 2 we have
( 3x +2)⁴ = ( 3x)⁴ + 4 [ (3x)³(2) ] + 6[ (3x)²(2)²] + 4 [ 3x(2)³ ] + 2⁴
Expand and simplify
That's
➢ ( 3x +2)⁴ = 81x⁴ + 4[ (27x³)(2) ] + 6 [ (9x²)(4) ] + 4 [ 3x(8) ] + 16
➢ 81x⁴ 4( 54x³) + 6(36x²) + 4( 24x) + 16
We have the final answer as
<h3>81x⁴ + 216x³ + 216x² + 94x + 16</h3>
Hope this helps you
I believe the slope is 2 if I’m not wrong
