Your answer is C

Area = length x width

Substitute in the values & expressions you know:

(12m + 18) = length x 6

Divide both sides of the equation by 6:

(12m + 18)/6 = length

2m + 3 = length

Please help me out with this!!

Answer:

see explanation

Step-by-step explanation:

Given

x + $\frac{1}{2}$ ≤ - 3 or x - 3 > - 2

Solve the left and right inequalities separately, that is

x + $\frac{1}{2}$ ≤ - 3 ( isolate x by subtracting $\frac{1}{2}$ from both sides )

x ≤ - 3 - $\frac{1}{2}$ , that is

x ≤ - $\frac{6}{2}$ - $\frac{1}{2}$ , thus

x ≤ - $\frac{7}{2}$

x - 3 > - 2 ( isolate x by adding 3 to both sides )

x > 1

Solution is

x ≤ - $\frac{7}{2}$ or x > 1

What is 3x+4= -15? How would you get a negative number?

bulgar [2K]

Answer:

$x=-\frac{19}{3}$

Step-by-step explanation:

$3x+4=-15$

$3x+4-4=-15-4$

$3x=-19$

$\frac{3x}{3}=\frac{-19}{3}$

$x=-\frac{19}{3}$

Help please!!! Thxxxxxx

Alika [10]

Answer:

40 degrees

Step-by-step explanation:

Angle ACO = 80 ( 180 - 100)

Angle CAO = 60 (180 - 120)

Angle AOC = 40 (180 - 80 - 60) (TOTAL DEGREES OF A TRIANGLE IS 180)
