15s^11-25s^4 factorised <br><br> plz tell me. :)
saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

5(3s^{11}-5s^4)

As for the literal part, you can factor s^4 because it's the power of s with the smallest denominator. So, we have

5s^4(3s^7-5)

An uncle wills 3000.00 to his 2 nieces and one nephew. The older niece is to receive twice what the younger niece receives and t
Semenov [28]

Answer:

Nephew receive 1500.00

Older niece receive 1000.00

Younger niece receive 500.00

Step-by-step explanation:

Let assume a variable x,y,z for the niece, older niece and the nephew respectively.

Y= 2x (Twice the younger niece)

Z= x + y. (Sum of the two nieces)

Since y = 2x

Z = x+2x

Z= 3x

Therefore:

X = 1x

Y = 2x

Z = 3x

So the will will be shared among them in the ratio

Nephew : older niece : younger niece

3 : 2 : 1

Nephew. 3/6 x 3000 = 1500.00

Older niece 2/6 x 3000 = 1000.00

Younger niece 1/6 x 3000 = 500.00
