Answer:
The equation is 
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same.
The general equation for an arithmetic sequence is:
Taking the mth term as reference, the equation can be written as:
t(4) = 8 and t(10) = 32
The common difference can be found:
So
Finding the first term:
So
So
The equation is
The correct answer is: [D]: " -3x⁶ − 4x⁵ + 2x² + 8x + 4 " .

Explanation:
________________________________________________
Given:
________________________________________________
" ( 4x² + 3x + 4) + ( -3x⁶ − 4x⁵ − 2x² + 5x) " ;
Rewrite as:
" ( 4x² + 3x + 4) + 1( -3x⁶ − 4x⁵ − 2x² + 5x) " ;
Note: The "1" is implied — since "1", multiplied by any value, is equal to that same value.
__________________________________________________
Note the "distributive property of multiplication" :
_________________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab <span>− ac ;
</span>_________________________________________________
So, consider the following portion of the expression:
_________________________________________________
" + 1 ( -3x⁶ − 4x⁵ − 2x² + 5x) " ;
= (+1 * -3x⁶) − (1 * 4x⁵) − (1 * 2x²) + (1 * 5x)
= − 3x⁶ − 4x⁵ − 2x² + 5x ;
Now, bring down the rest of the expression:
( 4x² + 3x + 4) − 3x⁶ − 4x⁵ − 2x² + 5x ;
= 4x² + 3x + 4 − 3x⁶ − 4x⁵ − 2x² + 5x
Combine the "like terms" ;
+ 4x² − 2x² = + 2x² ;
+ 3x + 5x = 8x ;
And we have:
" -3x⁶ − 4x⁵ + 2x² + 8x + 4 " ;
→ which is: Answer choice: [D]: " -3x⁶ − 4x⁵ + 2x² + 8x + 4 " .

Sin θ =
If θ = 51° ; opp = QR ; hyp = 17 cm
Then sin 51° =
⇒ QR = (sin 51°) (17 cm)
= 13.21 cm
∴ the answer is OPTION C
Answer:
its the on the botum left
Step-by-step explanation:
('o')
To equal the step 2, we would have to determine that 20 was our new denominator and multiply the first fraction by 5, the second by 4 and the 2 by 20.
multiplied by sides of the equation by 20
