Answer:

The third option: -24

Step-by-step explanation:

21 + $6^{2}$ - ( 35 - 8 ) · 3

So you need to solve this according to BEDMAS / PEMDAS (same thing)

Brackets/Parentheses, Exponents, Division/Multiplication, Addition/Subtraction.

Btw, don't worry about ( · ), it means multiplication ( × )

So according to BEDMAS / PEMDAS...

= 21 + $6^{2}$ - ( 35 - 8 ) · 3

= 21 + $6^{2}$ - 27 · 3

= 21 + 36 - 27 · 3

= 21 + 36 - 81

= 57 - 81

= -24

The answer to this question will be 45 because you minus 15 on both sides and get 45 for 60 minus 15 and then will minus 2x on both sides and the Equation will now be x=45 and you plug it in to check

What is the value of (-7 + 3i) - (2-6i)?

BigorU [14]

First you must distribute the minus sign to the number bolded bellow:

(-7 + 3i) - (2 - 6i)

(-7 + 3i) + (-2 + 6i)

-7 + 3i - 2 + 6i

Now you must combine like terms. Imaginary numbers can only combine with imaginary and real number can only be combined with real numbers:

(-7 + (-2) ) + (3i + 6i)

-9 + 9i

I hope this helped! Let me know if you have any questions :)

HELP someone please!!!! i dont understand

Answer:

x = 65.03°

Step-by-step explanation:

To solve for x, we have to apply trigonometric ratio.

Recall: SOH CAH TOA

From the diagram, we know the following:

Reference angle = x

Hypotenuse = 45

Adjacent = 19

Since we know the Hyp and Adj, we would apply CAH, which is:

Cos x = Adj/Hyp

Plug in the values

$cos(x) = \frac{19}{45}$

$x = cos^{-}(\frac{19}{45})$

x = 65.0250346°

x = 65.03° (nearest hundredth)
