-2

Step-by-step explanation:

So we want to find the value of:

Simply add:

Thus, drop the word SUM on -2.

Further notes:

To use the number line to solve, first start by placing your point on -6.

Since we are adding 4 to -6, we move to the right. Thus, move from -6 four spaces to the right.

If you do so correctly, you will end up at -2, the same answer we acquired previously.

Step-by-step explanation:

The sum is the result from adding two or more numbers to each other.

-6 is the starting point on the number line.

4 is added to -6, so an arrow from -6 goes 4 units to the right of the number line.

The arrow stops at -2.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
