Find the 12th term of the arithmetic sequence given a3=116 and a7=180<br>​
SOVA2 [1]

Answer:

Step-by-step explanation:

nth term = a +(n-1)d

a3 = 116 ;   a + 2d = 116 ---------(i)

a7 = 180;   a + 6d = 180 -------(ii)

multiply (ii) by -1. so a will be eliminated

           a + 2d = 116 ---------(i)

(ii)*-1    <u>-a - 6d = -180</u> -------(ii)   { Now add the two equations}

              - 4d = -64

                   d = -64/-4

                  d = 16

Plug in the value of d in equation (i),

a + 2*16 = 116

a + 32 = 116

        a = 116 - 32

        a = 84

12th term = 84 + 11* 16 = 84 + 176 = 260

Crazy boy [7]

Answer:

Amount of fencing: 32 feet

Amount of soil: 63 square feet

Step-by-step explanation:

Fencing: In a rectangle, the opposite side is the same length. So we do:

9+7+9+7 = <u>32 feet</u>

Soil: The soil is the area. Area is equal to length times width. Length is 9 and width is 7, so we do:

9 x 7 = <u>63 feet squared</u>

Find the angle measure of PQR
sineoko [7]

Answer:

<em>64 degrees</em>

Step-by-step explanation:

When you have the SRQ angle, you can easily solve for PQR. Luckily, we're given that QRP and PRS are 32 and 84, respectively. Adding this together gives you 116. 116*2 = 232 and 360-232 = 128, and 128/2 = 64.

<em>Please Mark Brainliest if this helps!</em>
