Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168
The answer is 11.265408 km.
To calculate the number of kilometers, we will use several conversions:
A) 1 mi = 63,360 in
B) 1 in = 2.54 cm
C) 1 cm = 0.00001 km
A) 1 mi = 63,360 in
7 mi = 63,360 in · 7 = 443,520 in
B) 1 in = 2.54 cm
443,520 in = 2.54 cm · 443,520 = 1,126,540.80 cm
C) 1 cm = 0.001 km
1,126,540.80 cm = 0.00001 km · 1,126,540.80 = 11.265408 km

Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Total money needed= $5,000
Percentage raised= 75%
<u>To calculate the amount collected and the difference required, we need to use the following formulas:</u>
Total collected= 5,000*0.75
Total collected= $3,750
Difference= 5,000 - 3,750
Difference= $1,250
