Answer:

g(5)= 103

Step-by-step explanation:

2x is 2(5)^2+3

2*5 is 10

10^2=100

100+3 = 103

For this case we have a function of the form y = g (x)

Where:

g (x) = 2x ^ 2 + 3

We must find g (5a), that is, substitute x = 5a:

Substituting: in the function we have:

g (5a) = 2 (5a) ^ 2 + 3\\g (5a) = 2 * 25a ^ 2 + 3\\g (5a) = 50a ^ 2 + 3

Finally, the answer is:

g (5a) = 50a ^ 2 + 3

Answer:

g (5a) = 50a ^ 2 + 3

-4 = x -1 can I see you work it out please?
kherson [118]
We need to get x alone, to do that we add 1 to both sides to cancel out the -1 on the right.
-4 = x -1
+1 +1
-3=x

This means x is equal to -3. Hope this helps!

miss Akunina [59]

Answer:

\large\boxed{\sf n^{th} \ term =3n}}

Step-by-step explanation:

Find common difference from subtracting any term in the sequence with the previous term.

\large{\sf 6-3}=3

Apply nth term formula.

\large{\sf a_n=a_1+(n-1)d

\large{\sf d=3 \ \ a_1=3}

\large{\sf a_n=3+(n-1)3

\large{\sf a_n=3+3n-3

\large{\sf a_n=3n}

Triangles G H L and K H J are connected at point H. Angles Angles L G H and H K J are congruent. Sides G H and H K are congruent
stira [4]

The congruence theorem that can be used is: B. ASA

<h3>What is the ASA Congruence Theorem?</h3>

If we have two triangles that have two pairs of corresponding congruent angles (e.g. ∠LGH ≅ ∠HKJ and ∠LHG ≅ ∠KHJ), and a pair of corresponding congruent sides (e.g. GH ≅ HK), the triangles are said to be congruent triangles by the ASA congruence theorem.

Therefore, triangles GHL and KHL in the image given are congruent triangles by the  ASA congruence theorem.
