Answer:

$a \: \: x = \frac{ -1 ± i\sqrt{139}}{14}$

Explanation:

Since this is unfactorable, use the Quadratic Formula:

$x = -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}$

Now, take the information and input it:

$-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\ \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ± i\sqrt{139}}{14}$

I am joyous to assist you anytime.

Virty [35]

Total height of the cake and the candles is 17.1 cm

Step-by-step explanation:

Step 1: Convert the mixed fractions into decimal expressions.

11 7/10 cm = 117/10 = 11.7 cm

5 4/10 cm = 54/10 = 5.4 cm

Step 2: Find total height of the cake and the candles

Total height = 11.7 + 5.4 = 17.1 cm

vova2212 [387]

Answer: x intercept is -3

y intercept is -9

Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept

6x+2(0)=-18

divide both sides by 6, and get -3 as an x intercept
