Hi! Let's get solving. :D

Okay.. This is a double bracket, so use the '' Waves '' method to expand the bracket. I don't mean to be lazy, but it's kinda hard to explain the working here, so here's a brilliant video that explains this method:

Answer:

X^2+4−5

Stay safe! :)

Note: I'm not a maths expert, please double check your answer.

If a person walks 1/3 a mile in each 1/2 hour, how far does he walk in 1 hour.

serg [7]

Distance travelled in 30 minutes = 1/3 miles

Distance travelled in 1 minute = 1/(3 × 30)

Distance travelled in 60 minutes = (1 × 60)/(3 × 30)

= 2/3 miles

Answer:

-13 $\frac{13}{25}$

Step-by-step explanation:

To multiply fractions with both the fraction and whole number you must convert it to an improper fraction by multiplying the whole numbers by the denominators, which you would get 35 for the first fraction and -10 for the second, then you must add the numerators to that number and put the number into the numerator spot. at this point you should have $\frac{39}{7}$ and $\frac{-12}{5}$ .

Now, multiply the numerators by the numerators and the denominators by the denominator and keep it aligned so the products stay in fraction form. now you should have $\frac{-468}{35}$ .

Divide the numerator by the denominator to get the whole number, in this problem that comes out to 13. The remainder of this division becomes the new numerator which in this case would also be 13 and the denominator stays the same so now you have -13 $\frac{13}{35}$ which is the answer
