Answer: $w^{2} + 13w + 36 = (w + 4)(w + 9)$

Step-by-step explanation:

$w^{2} + 13w + 36 = (w + 4)(w + ?)$

w (w + ?) +4 (w + ?)

w² + ?w + 4w + ?

4w + ?w = 13w

Subtract both sides by 4w

?w = 9w

? = 9

4 (?) = 36

Divide both sides by 4

? = 9

$w^{2} + 13w + 36 = (w + 4)(w + 9)$

Hope I helped!

Which of the following is the inverse of y=12^x

Elenna [48]

$y=12^x\ \ \ |log_{12}\\\\\log_{12}y=\log_{12}12^x\\\\\log_{12}y=x\log_{12}12\\\\x=\log_{12}y$

$y=12^x\to y^{-1}=\log_{12}x;\ x\in\mathbb{R^+}\to\ y^{-1}=\dfrac{\log x}{\log12};\ x\in\mathbb{R^+}\to y^{-1}=\dfrac{\ln x}{\ln 12}$

$Used:\\\\\log_aa=1\\\\\log_ab^n=n\log_ab\\\\\log_ab=\dfrac{\log_cb}{\log_ca}$

major each of the following angles write it measures right weather it is acute ,obtuse, right angle A straight angle or a reflex

Leya [2.2K]

Answer:

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle

Step-by-step explanation:

an acute angle is an angle less than 90 degrees

an obtuse angle is an angle more than 90 degrees

a right angle is an angle equivalent to 90 degrees (looks like two straight lines perpendicular)

a straight angle is an angle equivalent to 180 degrees (looks like a straight line)

a reflex angle is an angle greater than 180 degrees

so, ...

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle
