If you form a triangle with the points B and C as two of the points of the right angled triangle then you use Pythagoras to find the length of BC.

3^2+4^2=25
√25 = 5

We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent: 2^{5} = 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis 
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3×2^{5}+13(-2))+7(8-(4-9)=70+91=161
Final Answer=161

I need help with a function​
Sidana [21]

Answer:

one: 9

Two: D

Step-by-step explanation:

One

The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9

Two

The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.

-4(-2) + 3 = 8 + 3 = 11

3a

The function is decreasing over -4x + 3

It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing

3b

The function is a constant when x≥8. The value of the function is 9 no matter what x is.

3c

The function is increasing from - 2x to 8 which is going from -9 to 11
