I need help with 12 and 13 please! I really have to get this done :(

12. The length of the other base of the trapeziod is 5 feet.

13. A, B, & C

Step-by-step explanation:

12. Area: 36

    Height: 8

    Base 1: 4

B= 2(36) -4

       8

Step 1: Multiply 2 and 36; 72/8 - 4

Step 2: Divide 72 by 8; 9 - 4

Step 3: Subtract 9 and 4; B= 5

Solution: 5

13.

A. Area: 54       Height: 3        Base 1: 6   Base 2: 30

        30 = 2(54) - 6

                   3

        30 = 108/3 - 6

        30 = 36 - 6

        30 = 30

B. Area: 54    Height: 3         Base 1: 9          Base 2: 27

              27 = 2(54) - 9

                          3

             27 = 108/3 - 9

             27 = 36 - 9

             27 = 27 in

C. Area: 54     Height: 3         Base 1: 12        Base 2: 24

                  24 = 2(54) - 12

                          3

                  24 = 108/3 - 12

                  24 = 36 - 12

                  24 = 24 in

D. Area: 54     Height: 3         Base 1: 18      Base 2: 2

                        2 = 2(54) - 18

                                 3

                       2 = 108/3 - 18

                       2 = 36 - 18

                       2 ≠ 18

E. Area: 54        Height: 3      Base 1: 36          Base 2: 1

                              1 = 2(54)/3 - 36

                             1 = 108/3 - 36

                             1 = 36 - 36

                             1 ≠ 0

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest
