Answer:
Step-by-step explanation:
A) 3x²c² + 5xc² - 2c²
Factor c² from all terms in the expression.
c²(3x² + 5x - 2)
Factor 3x² + 5x - 2
c²(3x-1)(x+2)
B) x² + 6x + 9
x² + 3x + 3x + 9
Factor common terms.
x(x+3)+3(x+3)
Take x+3 common.
(x+3)(x+3)
C) x² - 9
x² -3²
Apply formula : a² - b² = (a+b)(a-b)
(x+3)(x-3)
The answer is add 35 and 52 and you will get 87 which was supposed to be the amount sold
<h2>
The required "option D. 9.6" is correct.</h2>
Step-by-step explanation:
In given figure,
AD = x, DB = 12, BE = 8 and EC = 10
To find, the value of x = ?
Use the Side-Splitting Theorem,
We know that,
⇒ 
⇒ x =
⇒ x = 
⇒ x = 9.6
∴ The value of x = 9.6
Thus, the required "option D. 9.6" is correct.

<u>Answer</u>
37.96875
<u>Explanation</u>
In geometric sequence we use the formula below to find the nth of a sequence.
Tn = ar⁽ⁿ⁻¹⁾
Where a ⇒ first term
n ⇒ the term we are looking for
T₆ = 5 × (3/2)⁶⁻¹
= 5 × (3/2)⁵
= 5 × 243/32
= 1215/32
= 37 31/32
= 37.96875
