What are the solutions to the equation 3x2 + 3x +7 = 0?

KATRIN_1 [288]

Answer:

x is equal to 0.94 and -1.94

Step-by-step explanation:

3x² + 3x + 7 = 0

9x² + 9x + 21 = 0

9x² + 9x + 2.25 = 18.75

(3x + 1.5)² = 18.75

3x + 1.5 = ±√18.75

3x = -1.5 ±√18.75

x = (-1.5 ±√18.75) / 3

x = 0.94, -1.94

Find all the values of x where the tangent line is horizontal.<br> 2x^3+36x^2+192x+12

Afina-wow [57]

At x = -4 and -8
Take the derivative of the given equation to find rate of change of the graph.
f'(x) = 6x^2 + 72x + 192
At a horizontal tangent, f'(x) = 0, so set the equation equal to 0 and solve. Eventually you get x = -4 and -8

Leokris [45]

Sa= bw+hw+lw+ $\frac{1}{2}bh$ (2)
SA=(12*4)+(16*4)+(20*4)+( $\frac{1}{2} 12*16*2$ )
SA= 28+64+80+(6*16*2)
SA=28+64+80+(96*2)
SA=28+64+80+192
SA=364 $cm^{2}$
