A will be 360/4
B will be pentagon
C will be 72
D will be hexagon
E will be 360/60
F will be 51.428571
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
B. D=0.25n + 25
D=total n=number of hours 0.25=price per hour 25=the one time fee
R - 3 < 5
r < 5 + 3
r < 8 Answer
Step (1) Flip the equation
−10x+6=y
Step (2) Add -6 to both sides
−10x+6+−6=y+−6
−10x=y−6
Step (3) Divide both sides by -10
−10x−10=y−6−10
