The correct answer is 4a^2 + 3ab
In order to find this, we can write the equation out as described and then follow the order of operations.
3a^2 - 2ab + 3b^2 - (-a^2 - 5ab + 3b^2) ----> Distribute the negative
3a^2 - 2ab + 3b^2 + a^2 + 5ab - 3b^2 ----> Combine like terms
4a^2 + 3ab

Scale in terms of cm to m= 1/5
In every meter there are 5 cm
Considering this, if the dimensions are 15cm and 20cm, you would need to multiply them by 5 to convert them to meters
15*5= 75 20* 5=100
Dimensions- 75ft by 100ft
<u><em>Answer:</em></u>
They are 4.7miles apart
<u><em>Explanation:</em></u>
Cross-multiply & Divide,
Solve for x,
2 × 12 = 24
24 ÷ 5.1 = 4.7
Fraction division is basically multiplication of a reciprocal.
For example (1/4)/(1/8) = (1/4)x(8/1)=2
Multiplication of the answer and the piece that divides (in this case 2 x 1/8), you should get the piece that is being divided (in this case 1/4). If that is correct, then your division is correct.
