Answer: 33/4
Step-by-step explanation:
2(4x+6)=78
8x+12=78
8x = 78-12
8x=66
X=66/8
x= 33/4
In another way,
2(4x+6)=78
4x+6=78/2
4x+6=39
4x=39-6
4x=33
x= 33/4 (Answer)
2x^3 + 3x^2 + x + 1
=2x^3 + 3x^2 + 3x^2 - 3x^2 + x + 1
=2x^3 + 6x^2 - 3x^2 + x + 1
=2(x^3 + 3x^2) - 3x^2 + x + 1
=2x^2*(x+3) - 3x^2 -9x + 9x + x +1
=2x^2*(x+3) - 3x(x+3) + 10x +1
=2x^2*(x+3) - 3x(x+3) + 10x + 30 - 30 +1
=2x^2*(x+3) - 3x(x+3) +10(x+3) -29
The first three terms can be divided by (x+3) evenly so the remainder is -29
The answer will be
-1.8h=-7.2-8.1
h=-15.3/-1.8
h=8.5
We have the equation:
432 into 85443 equals 197.784
Calculated to 3 decimal places.
