Answer:

x=\frac{2}{3}\pm\frac{\sqrt{26}}{3}i

Step-by-step explanation:

3x^2+10=4x\\\\3x^2-4x+10=0\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\x=\frac{-(-4)\pm\sqrt{(-4)^2-4(3)(10)}}{2(3)}\\ \\x=\frac{4\pm\sqrt{16-120}}{6}\\ \\x=\frac{4\pm\sqrt{-104}}{6}\\ \\x=\frac{4\pm2\sqrt{26}i}{6}\\ \\x=\frac{4}{6}\pm\frac{2\sqrt{26}}{6}i\\\\x=\frac{2}{3}\pm\frac{\sqrt{26}}{3}i

Answer:

\sum\limits^7_{n=1}(4n - 3)

Step-by-step explanation:

Given

1 + 5 + 9 + .....

Required

Write a definition

First, we derive a formula for the series using:

T_n = a + (n - 1)d

From the attached data;

a = 1

d = 5 - 1 = 4

So:

T_n = a + (n - 1)d

T_n = 1 + (n - 1) * 4

T_n = 1 + 4n - 4

Collect like terms

T_n = 4n - 4+1

T_n = 4n -3

So, the definition for first 7 terms is:

\sum\limits^7_{n=1}(4n - 3)

Jack has a bag of candy full of 3 strawberry chews and 17 cherry chews that he eats one at a time. Which word or phrase describe
IrinaVladis [17]

Answer:

seventeen out of twenty

Step-by-step explanation:

The phrase that describes this probability would be

seventeen out of twenty

This is because the bag has a total of 20 candies ( 3 strawberry chews and 17 cherry chews). If he randomly chooses one from the bag, he has a 17/20 chance of getting a cherry chew because there are 17 total cherry chews in the bag. If we were to change this fraction into a phrase it would be the phrase above in bold.
