Answer:
8x^2 + 5y + 1
Step-by-step explanation:
1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y
group like terms
= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 5y + 1 - 3 + 3
= 8x^2 + 5y + 1
Answer:
2 mins= 8 gallons 3 mins= 12 gallons 4 mins= 16 gallons 5 mins= 20 gallons 6 mins= 24 gallons

- t = 9 ft
Answer:
3
Step-by-step explanation:
A ( 2, 2 )
( x1, y1 ) = ( 2, 2 )
Here,
x1 = y1 = 2
B ( - 2, - 2 )
( x2, y2 ) = ( - 2, - 2 )
Here,
x2 = y2 = - 2
Distance formula : -
d = √ ( x2 - x1 )² + ( y2 - y1 )²
AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²
= √ ( - 2 )² + ( - 2 )²
= √ 4 + 4
AB = √8
The value of √8 is 2.828.
Roundoff to nearest 10 is 3.
