Answer:
see below
Step-by-step explanation:
sqrt(90)
We know that sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9*10)
sqrt(9) sqrt(10)
3*sqrt(10)
7,8 y 10 adios amigo esa es la respuesta que necesitas
3a + b = 54
3a + 9 = 54
3a = 54 - 9
3a = 45
3a / 3 = 45 / 3
a = 15
Choice C
(0,-2) is a point
put 0 into each equation and see if it gives you -2
A, c, d will give you -2
(2,0)
Only C gives you 0
