For perimeter just add the sides up.
a) P = 57 + 41 + 57 + 41 = 196 in
Ignore the 36 because it is not an edge
b) P = 56 + 73 + 92 = 221 in

For areas look for measurements at right angles and multiply them.
a) A = 57 x 36 = 2052 in^2
b) A = 1/2 x 56 x 73 = 2044 in^2
The half is needed because all triangles are half the area of a rectangle.

What are the first 3 terms in. t(n)=-2n+7

seropon [69]

Answer:

The first 3 terms of the sequence $t(n)=-2n+7$ are:

$5, 3, 1$

Step-by-step explanation:

Given the sequence

$t(n)=-2n+7$

Here $n$ represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

$t(n)=-2n+7$

$t(1)=-2(1)+7$

$t(1)=-2+7$

$t(1) = 5$

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

$t(n)=-2n+7$

$t(2) = -2(2) + 7$

$t(2) = -4 + 7$

$t(2) = 3$

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

$t(n)=-2n+7$

$t(3) = -2(3) + 7$

$t(3) = -6 + 7$

$t(3) = 1$

Therefore, the first 3 terms of the sequence $t(n)=-2n+7$ are:

$5, 3, 1$
