Answer:

A = 84 ft^{3}

Step-by-step explanation:

To find the area of a trapezoid, use this equation:

A = \frac{a+b}{2}h

a = top base

b = bottom base

h = height

Let's classify all the sides:

a = 4 ft

b = 10 ft

h = 12 ft

Now, let's plug all these into the equation:

A = \frac{4+10}{2} (12)

A = \frac{14}{2}(12)                                    Add what's in the numerator

A = 7(12)                                      Divide 14 by 2

A = 84 ft^{3}                                     Multiply 7 by 12

So, the area of the trapezoid is 84 ft^{3}.

Hope this helps!!

I need help with both problems. Which one is true or false and why
stepladder [879]

The first equation can be simplified down to 3 and -\frac{3}{2}[/tex]. Therefore, ">" is correct.

The second equation can be simplified down to 12 and 6.25. Therefore, "<" is incorrect. It should be ">".

Answer:

A₍ₙ₎ = - 74 + (n-1) x 6

Step-by-step explanation:

A₍ₙ₎ = A₍₁₎ + (n-1) x d

A₍₁₈₎ = 28 = A₍₁₎ + 17 x d  ..... (1)

A₍₄₀₎ = 160 = A₍₁₎ + 39 x d  .....(2)

(2)-(1)    132 = 22d

d = 6

A₍₁₎ = 28 - 17 x 6 = -74

formula: A₍ₙ₎ = - 74 + (n-1) x 6
