Answer:
B
Step-by-step explanation:
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
D
x = 29
Follow the directions: substitute 13 for y in the first equation.
x + 13 = 42
Subtract 13 from both sides of the equation.
x +13 -13 = 42 -13
the answer is 1
(-4-(-2)) divided by (-3-(-1))
7 + 6√2
