Answer:7x12= 84
Step-by-step explanation:
7x10=70
7x2=14
70+14=84
have a good day
(x²+x)(x²+5x+6) = x^4 + 6x³ + 11x² + 6x + 1 ≥0
f(x) = x^4 + 6x³ + 11x² + 6x + 1
f'(x) = 4x³ + 18x² +22x +6
racines x1 = -0,301 x2 = -1,5 x3 = -2,618
variations
x -2,62 -1,5 -0,3
f'(x) - 0 + 0 - 0 +
f(x) -inf \ 0 / \ 0 /
on voit que cette fonction st toujours positive
Answer:
Please look at the attachment for step by step guide and solution.
The constant term in the equation is -20 because you will always be subtracting 20 no matter how big x is
