The answer to the question
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
Exact Form: 1635/4
Decimal Form: 408.75
Mixed Number: 408 3/4
Answer:
A) 5 7/10 =7/2 = 3.5

5.78 =5 71/90
5.78 =5 26/33
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (4, 9) and (x₂, y₂ ) = (12, 20)
m = = → C
