Factor completely x2 − 8x 16. (x 4)(x 4) (x − 4)(x − 4) (x 4)(x − 4) (x − 2)(x − 8)

(x² - 8x + 16) = (x-4) (x-4)

Step-by-step explanation:

We have to factorize the given expression

(x²-8x+16)

(x² - 8x + 16 ) = x² - 2(4x) + 4²

                    = ( x-4)²

[As we know (a-b)² = a² + b² - 2ab]

so (x² - 8x + 16) = (x-4) (x-4) is the factored form of the given expression.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
