1) $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

Step-by-step explanation:

We need to solve the polynomials.

1) $(-2x+4)+(x-6)$

Solving:

$(-2x+4)+(x-6)\\=-2x+4+x-6\\Combining\,\,like\,\,terms:\\=-2x+x+4-6\\=-x-2$

So, $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$

Solving:

$(uv-3)+(4uv+1)$

Expanding:

$=uv-3+4uv+1\\Combining\,\,like\,\,terms:\\=uv+4uv-3+1\\=5uv-2\\$

So, $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$

Solving:

$(11x-8)-(2x+3)$

Expanding:

$=11x-8-2x-3\\Combining\,\,like\,\,terms:\,\,\\=11x-2x-8-3\\=-9x-11$

So, $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$

Solving:

$(x^2-4)-(x-2)$

Expanding:

$=x^2-4-x+2\\Combining\,\,like\,\,terms:\\=x^2-x-4+2\\=x^2-x-2$

SO, $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$

Solving:

$(12-3t-7t^2)+(1+3t-t^2)$

Expanding:

$=12-3t-7t^2+1+3t-t^2\\Combining\,\,like\,\,terms:\\=12+1-3t+3t-7t^2-t^2\\=13+0t-8t^2\\=-8t^2+13$

So, $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

What is the answer to 3v − 2 = 1

vitfil [10]

Answer:

−

3v-2=1

3v−2=1

Solve

Add

to both sides of the equation

−

3v-2=1

3v−2=1

−

3v-2+{\color{#c92786}{2}}=1+{\color{#c92786}{2}}

3v−2+2=1+2

Simplify

Add the numbers

3v=3

Divide both sides of the equation by the same term

3v=3

\frac{3v}{{\color{#c92786}{3}}}=\frac{3}{{\color{#c92786}{3}}}

33v=33

Simplify

If M is the set of all perfect squares that are less than 100 and N is the set of all positive numbers that are less than 15. wr

deff fn [24]

The sets of M and N are { 4 , 16 , 25 , 36 , 49 , 64 , 81 } and{ 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }

Set is a collection of elements or numbers or objects.

It is represented with the symbol '{}'

We have that;

M is the set of all perfect squares that are less than 100
N is the set of all positive numbers that are less than 15

M = { 4 , 16 , 25 , 36 , 49 , 64 , 81 }

N = { 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }

Thus, the sets of M and N are { 4 , 16 , 25 , 36 , 49 , 64 , 81 } and{ 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }
