7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)

Find one value of x that is a solution to the equation: (2x + 3)2 – 4(2x + 3) - 12 = 0

Flauer [41]

Answer:

x = 3/2

Step-by-step explanation:

(2x + 3)2 – 4(2x + 3) - 12 = 0

Simplify the equation then isolate for x.

Distribute over brackets:

(4x + 6) – (8x + 12) - 12 = 0

Combine like terms:

4x + 6 – 8x + 12 - 12 = 0

6 - 4x = 0

Isolate x:

6 = 4x

6/4 = x

Reduce the fraction:

6/4 = x <= divide top and bottom by "scale factor" of 2

3/2 = x

x = 3/2 <= having x on the left side is standard
