The equation tan2x + 1 = sec2x. true or false.​

can you take a photo of the screen?

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm

3xy cannot be combined with the others

2x, -5x and x are like terms

her total is 2

  -3+5=2
