A perfect square trinomial is
(square of one term) + (square of another term) + (double the product of the two terms)
i dont know if i can explain it right, but its kinda just like matching numbers to an equation with other numbers
google videos can explain it better and show
hope this help :)
Answer:
3√2
Step-by-step explanation:
First, combine all the numbers in the square root, and then square root the number provided:
√(3 + 3 + 3 + 3 + 3 + 3) = √18
When square rooting, first, find prime factors of the number, 18. If there are pairs, they will be combined into a whole number:
√18 = √(3 * 3 * 2) = 3√2
3√2 is your answer.

Answer:
Q19 - x = 7
Q20 - x = 24
Step-by-step explanation:
Q19.
75 + x + 8 = 90°
83 + x = 90°
x = 90 - 83
<u>x = 7</u>
<u>{</u>CHECK: 75 + 7 + 8 = 90°<u>}</u>
<u></u>
Q20.
3x - 6 + x = 90°
4x - 6 = 90°
4x = 96
x = 96 / 4
<u>x = 24</u>
<u>{</u>CHECK: 3(24) - 6 + 24 = 90°<u>}</u>
