424 is rounded to 420
19 is rounded to 20
420+19 is equal to 440
Answer:
-20
Step-by-step explanation:
5 - 25 is negative 20 and since V does not have a number attached to it you do not divide it by anything
I think it would be:
22 + x = 118 for your equation.
And then to solve, it would be:
22 + x = 118
-22 -22
x = 96
Average length of black mamba = 96 inches
However it is late where I am so my bad if that’s not what you needed
Answer:
4 cm²
Step-by-step explanation:
Area = ½.bh
b = base (cm²)
h = perpendicular height, i.e. BD (cm²)
