Simplify quantity x squared plus 5 x plus 6 end quantity over quantity x plus 2

a. x2 + 1
b. x2 − 1
c. x + 3
d. x − 3

c

Step-by-step explanation:

Given

Factor the numerator

x² + 5x + 6 = (x + 2)(x + 3) , thus

=

Cancel the factor (x + 2) on the numerator and denominator, leaving

= x+ 3 → c

C. x+3

Step-by-step explanation:

Simplifying

x²++5x+6/x+2

Firstly we need to factorize the numerator to have;

x²+5x+6

x²+3x+2x+6

(x²+3x)+(2x+6)

x(x+3)+2(x+3)

x+2(x+3)

The equation will now become;

(x+2)(x+3)/x+2

= x+2 will cancel out x+2 to have x+3 left which is the required function

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
