Expand and Simplify (2x + 1)(x - 2)(x + 3)

Mathematics
1 answer:
lesantik [10]3 years ago
5 0

Answer:

Answer is =2x^3+3x^2-11x-6

Step-by-step explanation:

First of all multiply first and second bracket.

=x(2x+1) -2(2x+1)

=2x^2+x-4x-2

=2x^2-3x-2

Now multiply 2x^2-3x-2 with (x+3)

=x(2x^2-3x-2) +3(2x^2-3x-2)

=2x^3-3x^2-2x+6x^2-9x-6

=2x^3+3x^2-11x-6

When the function f(x) = 3(5)x is changed to f(x) = 3(5)x + 22, what is the effect? (4 points) There will be no change to the gr
Dima020 [189]

Answer:

the y-intercept is 22 spaces higher.

Step-by-step explanation:

I don't know, what special operations you want to express with 3(5)x.

as it is written this simply means

3×5×x

no exponents or other special things are visible.

but it should not matter.

whatever is the first function is unchanged the first part of the second function.

so, the only difference is the "+ 22" part.

and that simply means that all y values (the functional result values) are increased by 22.

you know that "f(x) =" has the same meaning as "y =".

and with that also the y-intercept (the y value when x = 0, and therefore the point, where the curve intersects the y-axis) is increased by 22 spaces.

30 points! would really appreciate the help!
katrin2010 [14]

Answer:

Step-by-step explanation:

cos43=60/AC

AC=60/cos43=82.04

cos27=60/BC

BC=60/cos27=67.34

sin(90-43)/BC=sin(43+27)/AB

AB=BCsin70/sin47

AB=67.34sin70/sin47

AB=86.522

P=86.522+67.34+82.04

P=235.9m

Write the quadratic equation whose roots are 6 and -2, and whose leading coefficient is 4,
Zinaida [17]

Answer:

4x^2 - 16x - 48 = 0.

Step-by-step explanation:

In a factor form it is:

4(x + 2)(x - 6) = 0

Convert to standard form:

4(x^2 - 4x - 12) = 0

4x^2 - 16x - 48 = 0.
