Answer:

Step-by-step explanation:
we are given that

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

remember that,|a|•|x|=|ax| hence,

and we're done!
The best way to multiply complicated problems mentally* is to break them into chunks.
Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.
In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600
*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.
The x-intercept is 3 and the y-intercept is -2
Answer:
= (9 + h) /5
Step-by-step explanation:
One fifth means 1/5
Sum of 9 and h = (9 +h)
One fifth of sum of 9 and h = 1/5 x (9 + h)
= (9 + h) /5
