The answer is: " -3x² + 6 " .
_________________________________________________
Explanation:
_________________________________________________
(2x² + 3x - 4) + (8 - 3x) + (- 5x² + 2) =
2x² + 3x - 4 + 8 - 3x + 1(- 5x² + 2) ;
_____________________________
Note: 1(-5x² + 2) = - 5x² + 2 ;
______________________________
2x² + 3x - 4 + 8 - 3x + 1(- 5x² + 2) =
2x² + 3x - 4 + 8 - 3x - 5x² + 2 = ?
_____________________________
Combine the "like terms" ;
+2x² - 5x² = - 3x² ;
+3x -3x = 0
-4 + 8 + 2 = 6 ;
___________________________________________________
So, we have: " - 3x² + 6 " .

Answer:x=-14.75
Step-by-step explanation:
f(x) = -7x - 19=-19
g(x) = 0.75x + 4.25 =4.25
Answer:
3.55-3.59
Step-by-step explanation:
to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
So numbers that would be rounded off to 3.6 have to have an hundredth value equal or greater than 5
they include
3.55
3.56
3.57
3.58
3.59
Answer:
here,base=16*3+7/16
=55/16
=3.43
height =5*1+3/5
=8/5
=1.6
now use formula h*b/2
=3.43*1.6/2
=5.48/2
=2.74
Step-by-step explanation:
therefore area of triangle is 2.74
