Answer:
2x^2+2y^2+4y would be your answer
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
this indicates the sequence is geometric.
the recursive formula allows a term in the sequence to be found by multiplying the previous term by the common ratio r , that is
f(n) = - 3f(n - 1) if n > 1 : f(1) = - 3
Answer:
b. area = 18 square units
Step-by-step explanation:
area of a triangle = 1/2 * base * height
area = 1/2 (6+3) + (6-2)
area = 1/2 * 9 * 4
area = 18 square units
therefore the answer is b.
-10y^2
Explanation: when combining like terms everything cancels out except for -10y^2
Answer:
13.5
Step-by-step explanation:
The point with the missing coordinate is (?, 12), so the value of y is 12. Plug 12 into the equation in the place of y.
4x - 3(12) = 18
4x - 36 = 18
4x = 54
x = 54/4 = 13.5
