Answer:

-129

Step-by-step explanation:

2x+5=0

x=-5/2 [By the remainder theorem]

f(-5/2)=8(-5/2)^3+4(-5/2)^2+13(-5/2)+3

=-125+25-65/2+3

=-129.

6 1/20, 6.1, 6.07 greatest to least
Digiron [165]
First you multiply 6 by 20, then add 1 which we should now have 121, then 6.1 which would equal the 6 1/10, multiply 6 x 10 now we have 60 add the 1, we have 61. Now 6.07 would equal 6 7/100 which would now be 6 x 100, which we get 600...now as before remember this rule, when ever you do a mixed fraction you always add the numerator. So now we have 601.

So the answer would be 601, 121, and 61. Hoped this helped :)

What's the probability you will flip 3 coins in a row and they all land on HEADS?
liberstina [14]

Answer:

B. 1/8 chance

Step-by-step explanation:

Every time you flip a coin you have a 1/2 probability of landing on heads.

If you repeated the process three times in the row

It would be 1/2 x 1/2 x 1/2 = 1/8

The odds they all land on heads is 1/8

Which expression has a value that is equivalent to 5n+13 when n= -5
maks197457 [2]

Answer:

Option A is correct.

4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5

Step-by-step explanation:

Given the expression: 5n + 13

If n = -5

then, by substituting in given expression we get;

5(-5)+13 = -25+13 = -12

Option A:

4n + 8

Substitute the value of n = -5 we have;

4(-5) + 8 = -20 + 8 = -12

Option B:

2n + 2

then;

2(-5) + 2 = -10 + 2 = -8

Option C :

n^2+13

then;

(-5)^2+13 = 25 + 13 = 38

Option D:

n + 8

then;

-5 + 8 = 3

Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
