Pls help for 27b!!!!!!!
rodikova [14]

Step-by-step explanation:

\beta

is a root of the quadratic

4 {x}^{2}  - 10x + 5

This quadratic isn't factorable so use the quadratic formula

- b +  -  \sqrt{ \frac{b {}^{2}  - 4ac }{2a} }

The plus and minus sign after b means we going to have two roots.

The roots are

\frac{5 +  \sqrt{5} }{4}

and

\frac{5 -  \sqrt{5} }{4}

We subsitue those values for Beta.

27a.

\frac{5}{2}

Show work please I need help asap
rosijanka [135]

Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

  • keep in mind there’s an addition between the two

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2
