How many zero pairs must be added to the function
MakcuM [25]

1 zero pair of 25 was added to bring given function into vertex form.

<h3>What is a Zero Pair ?</h3>

A zero Pair is the set of two numbers which when added together gives 0.

The function given is

f(x) = x² -10x -4

To convert it into the vertex form

y = a(x-h)²  +k

f(x) = x² -10x +25 -25 -4

f(x) = x² -10x +5² -25-4

f(x) = (x-5)² -29

Therefore this is the given function's vertex form and

1 zero pair of 25 was added to bring it into that.

Therefore Option D is the answer.

The length of a rectangle is 5 m greater than the width. The perimeter is 150 m. Find the width and length.

Let the length of rectangle be l

breadth be b

so ,

b+5 = l

perimeter = 2 × ( l+b) = 150

2b + 5 = 75

b = 35

so l = 40

Find a counter example to show that each of these statements are false
AysviL [449]

Step-by-step explanation:

let's say, 7 - 4 = 3

that contradicts the statement that both numbers are odd.

no, they are 7, 4, with 4 being even (and not odd).

in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.

odd with odd always delivers an even result. as does even with even.
