Answer:
12x^2-2x-5
Step-by-step explanation:
(9x2 + 3x - 2) + (3x2 - 5x - 3)
Combine like terms
9x^2+3x^2+3x-5x-2-3
12x^2-2x-5
Sorry I couldn’t answer S,T, &F. But I hope with the other problems that I solved makes sense, in order for you to solve the other 3.
Answer:
9.46 X 10^12 kilometers
Step-by-step explanation:
We will solve this problem by applying s=vt formula.
Here, s= distance
v= 3X10^5 km/s
t= 365.25 days = 365.25 X 3600 X 24 = 31557600 seconds
Now, s= 3X10^5 km/s X 31557600 seconds = 9.46 X 10^12 kilometers
Answer: AAS
Step-by-step explanation:
Given: In ΔABC and ΔDEF
∠B≅∠E [right angle]
∠A≅∠D
![\overline{BC}\cong\overline{EF}](https://tex.z-dn.net/?f=%5Coverline%7BBC%7D%5Ccong%5Coverline%7BEF%7D)
As there is two angles and one non included side of ΔABC is congruent the two corresponding angles and one non- included side of ΔDEF, therefore, by AAS congruence rule.
ΔABC ≅ΔDEF
AAS congruence postulate :- Triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.
