Answer:
He will need 8.34 yards of fabric.
Step-by-step explanation:
Given that,
The length of the fabric, l = 2 2/3 yards = 8/3 yards
The width of the fabric, b = 1 1/2 yards = 3/2 yards
We need to find the piece of fabric Roberto needs. It is equal to the perimeter of the fabric such that,

So, he will need 8.34 yards of fabric.
Answer:
3rd Option: -1(x + 15)
Step-by-step explanation:
When we factor our a negative 1, we take the opposite signs of what is given:
-1(x + 15)
To check, we simply just redistribute to check if it matches the original expression:
-x - 15
So the 3rd option is the correct choice.
Answer:
10m+11
Step-by-step explanation:
Distance formula between 2 points (x1,y1) and (x2,y2)
D=

D=29 and one point is (-5,5) and the other is (k,0)
sub
29=

29=

square both sides
841=

841=

minus 25 both sides
816=

square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k
the possible values for k are
k=-5+4√51 or k=-5-4√51
