Answer:
2x3+15x2+25x−6
Step-by-step explanation:
Multiply each term in the first expression by each term in the second expression and combine like terms.
Solution:
Given: ABCD is a Rhombus
To Prove: ΔABC≅ΔCDA
Construction: Join AC as diagonal.
Proof: ABCD is Rhombus whose sides are equal and diagonal are perpendicular bisectors. Please see attach figure.
In ΔABC and ΔCDA
AB=CD (Side of same Rhombus)
BC=DA (Side of same Rhombus)
AC=CA (Common Side of both triangle)
Therefore, ΔABC≅ΔCDA by SSS property of congruence.
Hence Proved, ΔABC≅ΔCDA
I pooped mysels so can’t figure it out
Answer:
175.93 feet
Step-by-step explanation:
First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)
Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).
Now you subtract
254.47 - 78.54 = 175.93
Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.
