Lily should be correct because 4x7 will give you the same product no matter which way you do it. The zeros don't matter either. You could have 1,000,000 zeros but you're 4x7 or 7x4 will stay the same.

Explain the difference between finding rational zeros and finding all zeros.
r-ruslan [8.4K]

Answer:

see explanation

Step-by-step explanation:

Given the polynomial

p(x)=a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+...+a_2x^2+a_1x+a_o

The rational zeros are all the possible factors of a_0 dived by all the possible factors of a_n. Therefore we use the rational rots theorem to find all possible rational zeros.

To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.

Aahil, James and merav share £90 in the ratio 1:3:5 how much does merav get
Dafna1 [17]

Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.

To find: How much Merav gets.

Answer:

Let's assume the shares of each to be 'x'.

This implies that 1x + 3x + 5x = 90.

9x = 90

x = 90/9

x = 10

Substituting this value of x in the ratio,

  • 1 × 10 = 10 [<em>Aahil's share</em>]
  • 3 × 10 = 30 [<em>James' share</em>]
  • 5 × 10 = 50 [<em>Merav's share</em>]

Therefore, Merav gets £50.

Hope it helps. :)

Justify the last two steps of the proof.
Georgia [21]
Statement 3:

NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself).

Statement 4:

Shape MNO and shape PON are congruent by side-side-side since:

side PN = side MO
side MN = side PO
side NO = side ON
