Answer:
x=8
Step-by-step explanation:
(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)
(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1
4x²+2x+2x+1 = 5x²-4x+1
4x²+4x+1 = 5x²-4x+1
0= 5x²-4x²-4x-4x+1-1
0= x²-8x
x²-8x=0
x²=8x
x=8
Answer:
3x + 16 = 22.75

Hi there! The answer is 10 miles.
Let the distance be represented by b.
The cost if the ride will therefore be
$5 + ( $3.70 × d )
We end up with the following equation

Subtract 5 from both sides.

Divide both sides by 10.

Therefore, Emma had a taxi ride of 10 miles.
Answer:
(10x squared -4) - (7x squared +3)
