Answer:
BC = 3.6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
1.5 BC = 5.4 ( divide both sides by 1.5 )
BC = 3.6
Answer:
16)
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.

What is formula of sum of cubes and difference of cubes?</h3>
Formula of sum of cubes and difference of cubes are following
(a)
by comparison with formula we can say that this is neither sum or nor difference of cubes.
(b)
by comparison with formula we can say that this is neither sum nor difference of cubes.
(c)
we can say that this is neither sum nor difference of cube as it's difference of squares.
(d)
by comparison with formula this is equal to
Hence this is sum of cubes
(e)
by comparison with formula we can say that this is neither sum nor difference of cubes.

For this case we have the following quadratic equation:
The solutions will be given by:
Where:
Substituting the values we have:
We have two roots:
ANswer:
Answer:
4th term is 274.4 cm
5th term is 192.08 cm
Step-by-step explanation:
Here, we want to get the 4th and 5th term
Let us get the common ratio;
That would be ;
392/560 = 560/800 = 0.7
The 4th term will be ar^3
= 800 * 0.7^3 = 274.4
The 5th term will be ar^4
= 800 * 0.7^4 = 192.08
