1 answer:

3 0

P = 5 .............................................
this is how=

first you expand the second equation
25 + 4p = -18 + -12 + 6p + 9p

then you add the like terms in the second equation:
25 + 4p = -30 + 15p
then this is how=
25+30 = 15p -4p
55=11p

p= 5

Giving brainliest for correct awnser. Factor the expression below.

tresset_1 [31]

Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:

$x^2 + 18x + 81$

$x^2 +3x + 27x + 81$

Group:

$(x^2 +3x) (27x + 81)$

Take out GCF (Greates Common Factor):

x(x + 3) 27(x + 3)

(x + 27) (x + 3)

Radium 226, which had been used for cancer treatment, decays with a half-life of 1622 years. suppose there is a 6 gram sample of

sveticcg [70]

This is a relatively simple half life calculation.
To go from 6 to 3 grams, 1622 years is required.
3 to 1.5 grams another 1622 years is required.
So, it undergoes exactly 2 half-lives or 3,244 years.
