then cancel them down go from the front to the back so go like
1 then 5 then 1 again then 4 and etc
u would then end up with the last two numbers which is 3 and 3. if u had numbers like 5 and 7 u would have to find the number in the middle of which would be 6. in the case the two numbers you are left with is 3 and 3 since there both the same the answer would be 3
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
Your answer would be the last option, (6x² - 5)(x² + 2). This is because when you expand it, you get: 6x² × x² = 6x⁴ 6x² × 2 = 12x² -5 × x² = -5x² -5 × 2 = -10 Which are all the correct terms.
