It is not a special product formulas.
b.Difference of terms
It is of the form

It is not a special product formulas.
c.Perfect square trinomials
It is of the form

It is a special product formulas.
d.Difference of perfect squares
It is of the form


Therefore, it is a special product formulas.
Answer:
C
Step-by-step explanation:
y = mx + c
m = (y2 - y1 )/ (x2 - x1)
using (1 , 7) & (2,5)
y2 = 5 y1 = 7 so y2 -y1 = -2
x2 = 2 x1 = 1 so x2 - x1 = 1
m - -2/1 = -2
y = -2x + c
when x =1 y = 7
so 7 = -2 + c
=> c =9
y = -2x + 9
if ordered pairs (2, 5) and (4, 1) used
m = (1-5)/(4-2)
=> m = -4/2
=> m = -2
y = -2x + c
for x =2 y =5
5 = -2*2 + c
=> c = 9
y = -2x + 9
she would have got same equation
Answer:
x = 117 degrees
Step-by-step explanation:
A triangle has 180 degrees in total.
A straight line is also 180 degrees in total.
180 - 101 = 79
Angles inside the triangle
79 + 38 = 117
180 - 117 = 63
63 degrees is the missing angle
x = 180 - 63
x = 117
