Answer:
A,D,C would be your answers
Step-by-step explanation:
Answer:

Given:
- area = 18 cm²
- base = 6 cm
- height = (h + 1) cm
Substitute the given values into the equation and solve for h:



expand using distributive property of addition
:

subtract 3 from both sides:

divide both sides by 3:

<u>To verify</u>:
Half of the base is 3 cm.
If h=5, then the height of the triangle is 6 cm.
Multiplying 3 by 6 is 18.
This matches the given area, so we can verify that h = 5.
Answer:
9/8 or 1 1/8
Step-by-step explanation:
9/4 - 9/8
Need a common denominator, multiply 9/4 x 2/2
18/8 - 9/8
Subtract the top numbers
18-9 = 9
The eight stays the same
9/8 or 1 1/8
8 5 and 18 8
7 2 9 2
8 - 5 = 3, 8 - 7 = 1, 5 - 2 = 3 and 18 - 8 = 10, 18 - 9 = 9, 9 - 2 = 7, 8 - 2 = 6
