Answer:

x = -5/7 or x = 2

Step-by-step explanation:

7x² - 9x - 10 = 0

Factor the left side of the equation.

(7x + 5) (x - 2) = 0

Set the factors equal to 0.

7x + 5 =0

7x = -5

x = -5/7

x - 2 = 0

x = 2

Evaluate. –1.65 + (–3.4)
elena55 [62]
Hey there! 

This seems like a algebraic expression

SO,
Remember: negative and negative = positive
                      positive and positive = positive
                     positive and negative = negative
                       negative and positive = negative

In this problem we will be doing negative and negative so that means our answer will be a negative 

Firstly, lets line up our decimals to solve this problem (once when you do that , you can solve it easier)

-1.65 &#10;\\ +&#10;\\ (-3.4)&#10;

Answer: 
-5.05

Good luck on your assignment and enjoy your day
