So there isn’t an exact answer however, this is what I got: 0.006345177664975
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27
30kx-6kx=8
24kx=8
x=8/(24k)
x=1/(3k)
so the answer should actually be D
(4x2-2x)(3x2-2x+1)=
(8-2x)(7-2x)=
56-16x-14x+4x^2= (^2 means squared ;) )
4x^2-30x+56
