Select the two values of x that are roots of this equation. x^2+2x-4=0

GuDViN [60]

Answer:

$\large\boxed{x=-1\pm\sqrt5}$

Step-by-step explanation:

$x^2+2x-4=0\qquad\text{add 4 to both sides}\\\\x^2+2x=4\\\\x^2+2(x)(1)=4\qquad\text{add}\ 1^2=1\ \text{to both sides}\\\\\underbrace{x^2+2(x)(1)+1^2}=4+1^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+1)^2=5\to x+1=\pm\sqrt5\qquad\text{subtract 1 from both sides}\\\\x=-1\pm\sqrt5$

Your straight-time pay is $195.

Maguire, M. 10.25 243

Reyes, A. 14.525 31.125

Lily’s sister has a bag of skittles containing 3 yellow skittles, 4 red skittles, 5 green skittles, and 3 orange skittles. What

lisov135 [29]

Answer:

Read a bit so you can understand which one you want.

Percentage

15 skittles, 3 of the 15 are orange.

3 over 15, or 0.2 as a percentage.

So there is a 0.8% chance that he will NOT pick an orange skittle.

Fraction

15 skittles, 3 over 15.

3 over 15 can be 1 over 5.

So there is a 4 over 5 chance that he WONT grab an orange skittle, pretty good odds.

Marianna [84]

Answer:

f(x)=2x^2+3

Step-by-step explanation:

If you see the f(x), you can see that it is squished by a factor of 2, and it is translated upwards 3 units. that means that the final equation is f(x)=2x^2+3, which is B
