Step-by-step explanation:
The adjacent should be 16, 39 is the hypotenuse
Ax^2+bx+c
if a=1, then
take 1/2 of b and square it
w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2
to make it into perfect squres, add 4
Answer:
5 weeks
Step-by-step explanation:
12x + 105 = 165 ---> subtract 105 on each side-----> 12x = 60----> divide by 12 on each side -----> x = 5
Answer:
a_1 = 6
a_n = 5 × a_n-1
Step-by-step explanation:
30/6 = 5
150/30 = 5
750/150 = 5
The rule is to start with 6 and multiply each number by 5 to get the next number.
a_1 = 6
a_n = 5 × a_n-1
