Mr. knotts found the difference of the following expression. which statement is true about mr. knott's work?
step 1: (x+ 1}x=15 +1
1(x+1)
step 2: (x + 1)(x-1)
(x + 1)(x-1)
x-x+1
step 3: (x + 1)(x-1)
step 4
(x+ 1)(x-1)

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information
