The answer for 7/12-4/12 is 1/4!
Answer:
Reflection across the x-axis
Step-by-step explanation:
Ax +c/3 =d now we can make crisscross
ax+c =3d now find value of x
ax=3d-c positive c become negative when I turn to other equal side
so
ax=3d-c
x=3d_c/a
45+55=100 180-100=80 that makes y = 80, and vertical angles makes x=80
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
