7 0

Answer:

Step-by-step explanation:

Remark

√80 =  √(16 * 5) = 4√5      I will put the - sign in when I gather terms

√45 = √(9 * 5) = 3√5

Expression

4√5x - √80x+√45x

Solution

4√5x - 4√5x  + 3√5x

The first two terms cancel out

3√5x is all that is left

Answer: 3√5x

To cover a rectangle region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. W
gulaghasi [49]
We know that the perimeter of a rectangle is 2(width)+2(length). We can multiply the length by 2 to find out how much remaining fencing we have, then divide that number by 2 to find the width.

15.5*2=31
170.5-31=139.5
139.5/2=69.75

A possible width is 69.75 feet.
