Answer:
D. 5y^2
Step-by-step explanation:
2x + 3y^2 - 2(x - y^2)
2 * x = 2x
2 * -y^2 = -2y^2
2x + 3y^2 - 2x + 2y^2
Combine like terms
2x and -2x cancel ach other out
3y^2 + 2y^2 = 5y^2
D. 5y^2
Answer:
A
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
The perimeter is the sum of the lengths of the base and the two equal legs:
51 = x + 2(3x -6)
51 = 7x -12 . . . . . eliminate parentheses
63 = 7x . . . . . . . . add 12
9 = x . . . . . . . . . . divide by 7
To find the length of the border, you will need to find the circumference of the circular area that us formed.
C = pi x d (double the radius to find the diameter)
3.14 x 10 yards
C = 31.4 yards.
Kiyo will need approximately 31.4 yards of border.
