Use order of operations (PEMDAS)

-3^2 + (-6)(10)

= -9 +(-4)(10)

= -9 - 40

= -49  (answer).

Can someone explain what to do like im a 5 year old please? (pre algebra)
QveST [7]

Answer:

angle 3 = 61

angle 4 = 119

angle 6 = 61

angle 7 = 119

Step-by-step explanation:

there are a few ways you could look at this

first, each angle that is diagonal from eachother is going to be equal so 1 is the same as 3, 2 is the same as 4 etc

also each line going across has to be 180° so if angel 1 was 175 then angle 2 has to be 5 so when you combine them it becomes 180

if you look at the sizes some are bigger than the others, because you're given angle 1 = 61 then all the other small angles would be 61 too, and 180 - 61 = 119 so the all the big ones have to be 119

if this confused u more I'm sorry lol let me know if this helped

Rewrite the function by completing the square.
Anna [14]

Answer:

y = x^2+14x +(14/2)^2 +8 - (14/2)^2

And solving we got:

y = x^2 +14x +49 + 8 -49

And we can reorder the terms we got:

y =(x+7)^2 -41

And that would be the equivalent expression for the problem

Step-by-step explanation:

For this case we have the following function given:

y = x^2 +14x +8

And we can complete the square adding the middle of 14 squared and subtracted before like this:

y = x^2+14x +(14/2)^2 +8 - (14/2)^2

And solving we got:

y = x^2 +14x +49 + 8 -49

And we can reorder the terms we got:

y =(x+7)^2 -41

And that would be the equivalent expression for the problem
