You can find the dimensions of the model and plug them into the formula for volume (length x width x height)
I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
Answer:
19
Step-by-step explanation:
4(4)+3
16+3=19
You need to isolate the variable <em>h</em>.
1) Subtract both sides by 2.
-4h + 2 = 18
-4h + 2 - 2 = 18 - 2
-4h = 16
2) Divide both sides by -4 (the coefficient).
(-4h) / -4 = 16 / -4
h = -4
The answer would be 5.
When adding a negative to a positive, it's the same thing as subtracting.
