Y=5+4x
Because it is 5 dollars when you enter and then 4 dollars per round
11 = w - 12
11 + 12 = w -12 + 12
w = 11 + 12
w = 23
25 a² + 20 ab + 4 b²
for formula

find u,v such that: u.v = a
and u+v = b then group according to

=

factor out 5a from :

factor out 2b from :

=

factor out :

Answer:
3125
Step-by-step explanation:
12.5x25x10
312.5x10
3125cm
so your answer will be D
X^3 - 21x = -20add 20 to both sidesx^3 - 21 x + 20 = 0Rational Root Theorem:Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20------------------------------- Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
