Answer:

68

Step-by-step explanation:

The formula of a trapezoid is (b1+b2)/2 x the height.

You first add the two bases: 17

Divide by 2: 17/2 = 8.5

Now, the height is 8.

So now multiply.

8x8.5=68

Hope this helps!

Consider the first four terms of the sequence below. -3, -12, -48, -192, . . . What is the 8th term of this sequence? A. -49,152
kolbaska11 [484]

Answer:

A

Step-by-step explanation:

there is a common ratio between consecutive terms , that is

- 12 ÷ - 3 = - 48 ÷ - 12 = - 192 ÷ - 48 = 4

this indicates the sequence is geometric with nth term

a_{n} = a₁ r^{n-1}

where a₁ is the first term and r the common ratio

here a₁ = - 3 and r = 4 , then

a₈ = - 3 × 4^{7} = - 3 × 16,384 = - 49,152
