It's 24k-6
By order of operations, you do the multiplication first: 3k(4) = 12k
12k-6+12k now combine like terms
24k-6
Hope that helps
Let a, b and c be in a geometric sequence, then ac = b^2
Hence, (2k + 1)(7k + 6) = (3k + 4)^2
14k^2 + 19k + 6 = 9k^2 + 24k + 16
5k^2 - 5k - 10 = 0
5k^2 + 5k - 10k - 10 = 0
5k(k + 1) - 10(k + 1) = 0
(5k - 10)(k + 1) = 0
5k - 10 = 0 or k + 1 = 0
5k = 10 or k = -1
k = 2 or k = -1
The geometric sequence formed is
2(2) + 1, 3(2) + 4, and 7(2) + 6
5, 10, and 20
OR
2(-1) + 1, 3(-1) + 4, and 7(-1) + 6
-1, 1, and -1

Plz mark me!!! Have a great day :)
I’m this you should know that it is best to find the area of each triangle then add them together
As you see the base is 24 so you take half of 24 for the base of your triangles and you get 12
1/2 is one half
TRIANGLE A
A = 1/2( Base (times) height)
A = 1/2(12 (times) 35) = 210
The formula will be the exact same for the other triangle.
When adding the areas up you get 420 squared inches.
Therefore answering is 420 in^2
