Please please please help me and explain how you did it!!

The third option: -24

Step-by-step explanation:

21 + - ( 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 + - ( 35 - 8 ) · 3

= 21 + - 27 · 3

= 21 + 36 - 27 · 3

= 21 + 36 - 81

= 57 - 81

= -24

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
