CD= 12 I think if its wrong I'm so sorry

I'm guessing that CD would be the 'altitude' of the of the right triangle, also considered as a leg, too, with also AB being the hypotenuse. If this is the case, then CD would measure 4√3. Hope this helps.

1.Solve the inequality (x-2)(x+1) ≥ 0 .

scoray [572]

Answer:

#1: inequality form: x ≤ –1 or x ≥ 2

interval notion: ( -∞,-1] U [2,∞)

#2: false/no solution

#3: A) point form: (3,9)(-1,1)

equation form: x= 3,y=9 and x= -1,y=1

B)point form: (1,7)(7,1)

equation form: x=1,y=7 and x=7,y=1

Step-by-step explanation:

#1: solve for x by simplifying both sides of the inequality, then isolating the variable.

#2: N/A

#3: solve for the first variable in one of the equations, then substitute the results into the other question.

Which of the following is equivalent to the expression below? log 3-log 15

Nikitich [7]

Answer:

$C. =log\frac{1}{5}$

Step-by-step explanation:

Formula =======================

consider a and b two real numbers

where a > 0 and b > 0.

$log\frac{a}{b} =loga-logb$

……………………………………………………………

log 3 − log 15

$=log\frac{3}{15}$

$=log\frac{3}{3\times 5}$

$=log\frac{1}{5}$
