Answer:
NOT CONGRUENT
Step-by-step explanation:
Given:
AB ≅ CD
∠DCB ≅ ∠DAB
To prove:
ΔABD ≅ ΔDCB
Statements Reasons
1). AB ≅ CD 1). Given
2). ∠DCB ≅ ∠DAB 2). Given
3). DB ≅ DB 3). Reflexive property
4). ΔABD ≅ ΔDCB 4). SSA property of congruence.
But in the given options SSA property is not given.
So the answer is NOT CONGRUENT.
The answer is B: 150
Let a be the age at which the tree reaches maturity
289000 = 900a + 2200(220-a)
289000 = 900a + 484000 - 2200a
289000 - 484000 = -1300a
a = -19500 / -1300
a = 150
Let's look at the way each of these attempts to simplify our expression.
Answer A simply mulltiplies the 4 and the 7 to get 28. <em>This is the correct answer</em>.
The reason you can't just do squaring (to the power of 2) and then go to the power of x later is because you would write that as
, not
.
Degree is the highest power of the polinomail
since higest poer is p^3, 3 is higest poer=degree
3rd degree
Answer:
It decreases by 21% in circulation.
Step-by-step explanation:
In order to find the percentage decrease, first, you have to find the difference of the circulation of a newsletter :
Then, you have to divide by the original amount and multiply by 100 :
