Answer: 2a^2+22a+−1
Step-by-step explanation:
Let's simplify step-by-step.
2a^2−5a+(9)(3)a−1
=2a^2+−5a+27a+−1
Combine Like Terms:
=2a^2+−5a+27a+−1
=(2a^2)+(−5a+27a)+(−1)
=2a^2+22a+−1
Step-by-step explanation:
We can prove that the triangles are congruent using the SAS method.
It's given that GH and JH are congruent (S)
Angle GHF and Angle IHJ are equal since they are vertically opposite (A)
It's given that FH and HI are congruent (S)
Thus, the triangles are congruent, which implies that the remaining sides are equal.
------------------------------
(75c^2d^4f^8)/(15cd^3f^4)
75/15 x c^2d^4f^8 over cd^3f^4
5 x c^2d^4f^8 over cd^3f^4
5c^2-1d^4-3f^8-4
5c^1d^4-3f^8-4
5c^1d^1f^8-4
5c^1d^1f^4
5cd^1f^4
5cdf^4 or option A.
------------------------------
Since it costs $4, you will have $17.50 left to go on rides. $17.50 divided by $2.50 is 7. So you can go on 7 rides.
8 because we multiply 4by 2
