Answer:

answer maybe x^2 + 3x - 28

explanation

first of all this is how any number of such a kind shud be written

ax^2 + bx + c

so that rearrange it

7x^2 + 3x -4

but I personally would go further to put it like this

x^2 + 3x - 28

both answers are the same so but maybe one is more considered since ur qn requires standard form

in case of any misunderstanding plizzz reach out for further explanation

hope this helps

Which is the best interpretation of the solution set for the compound inequality?
saw5 [17]

For this case we must find the solution set of the given inequalities:

Inequality 1:

3 (2x + 1)> 21

Applying distributive property on the left side of inequality:

6x + 3> 21

Subtracting 3 from both sides of the inequality:

6x> 21-3\\6x> 18

Dividing by 6 on both sides of the inequality:

x> \frac {18} {6}\\x> 3

Thus, the solution is given by all the values of "x" greater than 3.

Inequality 2:

4x + 3

Subtracting 3x from both sides of the inequality:

4x-3x + 3

Subtracting 3 from both sides of the inequality:

x

Thus, the solution is given by all values of x less than 4.

The solution set is given by the union of the two solutions, that is, all real numbers.

Answer:

All real numbers

I need to find the formula for these shaded squares
vaieri [72.5K]

For the given sequence we have the formula:

Sₙ = 1 + (n - 1)*2

The 50th square will have 99 shaded squares.

<h3 /><h3>How many shaded squares are on the n-th square?</h3>

Here we have a sequence:

The first square has 1 shaded squares.

the second square has 3 shaded squares.

The third square has 5 shaded squares.

And so on.

Already you can see a pattern here, each next step we add 2 shaded squares, then we can write the formula:

Sₙ = 1 + (n - 1)*2

Where S is the number of shaded squares and n is the number of the figure.

Then the 50th square will have:

S₅₀ = 1+ (50 - 1)*2  1 + 49*2 = 99
