What is the negative GCF for-3x -18?
Debora [2.8K]

Answer:

-3

Step-by-step explanation:

GCF = greatest common factor

What is in common with 3x and 18? They are both multiples of 3.

3 times x = 3x

3 times 6 = 18

However, it is -3x and -18

So we can add a negative sign in front of the 3

Therefore, the GCF is -3.

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)

How do I solve this?
iris [78.8K]

Answer:

Step-by-step explanation:

From the picture attached,

Addition of the blocks in first row is 60

a + a + a + 12 = 60

3a + 12 = 60

3a = 60 - 12

3a = 48

a = 16

For second row,

(b + 5) + (b + 5) + (b + 5) + (b + 5) = 60

4(b + 5) = 60

b + 5 = 15

b = 10

For third row,

(a + b) + c = (b + 5) + (b + 5) + (b + 5)

a + b + c = 3(b + 5)

16 + 10 + c = 3(10 + 5) [Since, a = 16 and b = 10}

26 + c = 45

c = 45 - 26

c = 19

For fourth row,

3c + d = 60

3(19) + d = 60

57 + d = 60

d = 60 - 57

d = 3
