Answer:
4x + 4y + 12
Step-by-step explanation:
x + 3y − y + 3x + 2(2 + 4 + y)
Apply Distributive Property:
2(2 + 4 + y)
2*2=4
2*4=8
2*y = 2y
x + 3y − y + 3x + 4 + 8 + 2y
Combine Like Terms:
x + 3x +2y +3y - y + 4 + 8
4x + 4y + 12
Since 5=15/3
5^x = (15/3)^x = 15^x / 3^3
Choices A and D
Answer:
√85
Step-by-step explanation:
The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...
... d = √((x2-x1)^2 +(y2-y1)^2)
For your points (-1, -4) and (-8, 2), the distance is ...
... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)
... d = √85
The distance between the two points is √85.
