Answer:
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Side a = (8.3f + 9.6g)
Side b = (3.6f + 1.5h)
Side c = (6.7h - 2.9g)
Perimeter of a triangle = side a + side b + side c
= (8.3f + 9.6g) + (3.6f + 1.5h) + (6.7h - 2.9g)
= 8.3f + 9.6g + 3.6f + 1.5h + 6.7h - 2.9g
Collect like terms
= 8.3f + 3.6f + 9.6g - 2.9g + 1.5h + 6.7h
= 11.9f + 6.7g + 8.2h
Perimeter of a triangle = (11.9f + 6.7g + 8.2h) cm
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Answer:
C. 5 3/10
Step-by-step explanation:
After adding the red strips count up the yellow blocks (13 in all)
take away 10 because that makes 1 whole
3 left over out of that 10
4 red strips + 10/10 + 3/10 = 5 3/10
It’s doesn’t satisfy the equation
Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.
