Answer:
20x^2−2x−6
Step-by-step explanation:
(4x+2)(5x+−3)
=(4x)(5x)+(4x)(−3)+(2)(5x)+(2)(−3)
=20x2−12x+10x−6
=20x2−2x−6
The two girls did not travel the same distance, because 0.07 is seven hundredths (7/100), and it is less than 7/10. ;)
Assuming the x stands for multiplication... follow the ordering rules:
First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:
3x16 - 36 + 4 - 6x4
Now do the multiplications:
48 - 36 + 4 - 24
The rest is just addition and subtraction
48 - 36 + 4 - 24 = -8
Full turn: 360 degrees
360/45=8
8 45 degree turns for a full 360 degrees turn
U.S customary system also known as the English system.
Founded by the British, but they dropped it. Now only three countries in the world still use this system.
