Wxyz is a rectangle. what are the coordinates of x and z? a. x = (a, 0) z = (0, b) b. x = (0, a) z = (0, b) c. x = (b, a) z = ( −a, −b) d. x = (b, 0) z = (a, 0) here is the link to the picture:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
