Answer: On Friday, he spend the least amount of time on the running machine.

Step-by-step explanation:

Since we have given that

Monday 0.3 = $0.3* 100\%=30\%$

Tuesday = 15%

Wednesday = $(1)/(6)* 100\%=16.67\%$

Thursday = $0.2* 100\%=20\%$

Friday = $(1)/(8)* 100\%=12.5\%$

Hence, we can compare all the days, and we get that

On Friday, he spend the least amount of time on the running machine.

Factorise p^-6p+8

Explanation would be helpful too. Thank you so much.

Answers

assuming you meant
p^2-6p+8
then
find what 2 numbes multiply to get 8 and add to get -6
numbers are -2 and -4
(p-2)(p-4)

(p-4)(p-2)

The 2 numbers have to add up to make the -6
-2+-4=-6
and they have to multiply together to make 8
-2 x -4 = 8

hope this helps!

Answer:

4 sqrt(5)

Step-by-step explanation:

7 sqrt(5) - 3 sqrt(5)

These are like terms so we can subtract

4 sqrt(5)

Final answer:

To simplify a radical expression 7√5 - 3√5, subtract the coefficients and keep the radicand the same. The simplified expression is 4√5.

Explanation:

To simplify the given expression, we need to combine the terms involving square roots. We can notice that the terms have the same radicand, which is 5. So, we can combine them by subtracting the coefficients. The simplified expression is:

7√5 - 3√5 = (7 - 3)√5 = 4√5
