Remark

The key to this one is just to remove the brackets. Be very careful with the right hand bracket.

Remove the brackets.

3a^2 + 1 - 4 - 2a^2 Notice the minus sign affects both the 4 and the 2a^2

3a^2 - 2a^2 = a^2

+ 1 - 4 = - 3

Answer

a^2 - 3

Starting with the definition 1.00in. = 2.54 cm, find the number of kilometers in 7.00mi . Please describe conversions.
ella [17]
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
