(2.1)(0.031) + 2 = 2.0651
23.) Substitute values into equation
(y) + (x)2
(0.031) + (2.1)2 = 4.231
Answer:
17
Step-by-step explanation:
- midpoint means half
- Let's name side 15 as A,11 as B and 8 as C
- 0.5 of A is 0.5×15=7.5
- 0.5 of B is 0.5×11=5.5
- 0.5 of C is 0.5×8=4
- Perimeter of small triangle =A+B+C
- 7.5+5.5+4=17
