X+5=9
subtract 5 from each side
x=4
<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
The lateral surface area of the cube can be determined using the formula,
where a is the side length.
Substituting a = 1.8 in the above formula, we get;
Squaring the term, we get;
Multiplying, we get;
Thus, the lateral surface area of the cube is 12.96 cm²
<span>Use the definition of continuity.
A function is continuous at a point x = a iff
lim [x → a] f(x) = f(a)
In other words, a function is continuous at a point if its value is equal to its limit at that point.
So, for f(x) to continuous at x = 4 we must have
lim f(x) = f(4)
x → 4

The sqft for an area that is 12 by 25 is 300.
2.60 x 300 = 780
It would cost $780.00.
Hope it helps!
<span>The answer to this question would be: 2.5 minute
In this question, when Sam started to run Leo was already 100 meters away. But Sam runs 105m/min which was faster than Leo(65m/min).
Then the time needed for Sam to catch up Leo should be:
time= distance / (Sam speed-Leos peed)
time= 100m/ (105-65m/min)
time= 100m/(40m/min)= 2.5min
