Factor the polynomial completely: x2 + 16

a) (x + 4)(x + 4)
b) (x - 4)(x - 4)
c) (x + 4)(x - 4)
d) cannot be factored

D)cannot be factored

Step-by-step explanation:

According to symbol-ab and math-way solve this cannot be factored.

hope this helps

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
