Answer:

30\: m^2

Step-by-step explanation:

For triangle:

Base = (4 + 3 +1) m = 8 m

Height = 9 m

For rectangle:

Length = 3 m

width = 2 m

Area of shaded region = Area of triangle - Area of rectangle

=  \frac{1}{2}\times base\times height-length \times width \\\\=  \frac{1}{2}  \times (4 + 3 + 1) \times 9 - 3 \times 2 \\  \\  =  \frac{1}{2}  \times 8 \times 9 - 6 \\  \\  = 4 \times 9 - 6 \\  = 36 - 6 \\  = 30 \:  {m}^{2}

Sidana [21]

Answer:

2 and 2/3 inches

Step-by-step explanation:

v = l x w x h

\frac{32}{45} = \frac{4}{5} · \frac{1}{3} · h

\frac{32}{45} = \frac{4}{15} h

cross-multiply to get 45 x 4 x h = 32 x 15

180h = 480

Anybody good in pre Calculus and know how to do #3 or #4?
lys-0071 [83]

Answer:

3. 0

4. n = -2

Step-by-step explanation:

I haven't taken pre-calc but this looks a lot like algebra.

For #3, just plug in -2 for the x values, so:

x^2 + 4x +4

(-2)^2 + 4(-2) + 4

= 4 - 8 + 4

= 0

For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):

5n + 6 = -3n - 10

add 3n to both sides

8n + 6 = -10

subtract 6 from both sides

8n = -16

divide both sides by 8

n = -2
