Step-by-step explanation:
3*sqrt(128) - 2sqrt(6)*4sqrt(3)
3*sqrt(128) = 3*sqrt(64*2) But the square root of 64 = 8
3sqrt(128) = 3*8 * sqrt(2) = 24 sqrt(2)
==================
2* sqr(6)*4sqrt(3) Combine the 2 and 4 = 8. Break apart the 6.
8* sqrt(3*2)*sqrt(3) Break apart the sqrt(3*2)
8*sqrt(3*2)*sqrt(3) = 8 * sqrt(3)*sqrt(2)*sqrt(3) but sqrt(3)*sqrt(3) = 3
8*sqrt(3)*sqrt(2)*sqrt(3) = 8*3*sqrt(2) = 24sqrt(2)
===================
24sqrt(2) - 24*sqrt(2)

Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2

Answer:
(A)30
(D)15
Step-by-step explanation:
Factors of 30 are 1,2,3,5,6,10,15 and 30
A composite number is any number that is not prime.
From the given options, the factors of 30 are 30, 5 and 15.
However, <u>5 is not a composite number.</u>
Therefore, the number that Lacey could be thinking of will either be 30 or 15.
