(5e^2- e - 7) - (-2e^2+ 3e + 4)

7e^2-4e-11

Step-by-step explanation:

(5e^2-e-7)-(-2e^2+3e+4)

5e^2-(-2e^2)-e-3e-7-4

5e^2+2e^2-4e-11

7e^2-4e-11

Step-by-step explanation:

5e^2-e-7+2e^2-3e-4

7e^2-4e-11

7e^2+7e-11e-11

7e(e+1)-11(e+1)

(7e-11)(e+1)

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
