Answer:

6x + 3h

Step-by-step explanation:

F(X) = 3x^2

F(X+h) = 3(X+h)^2

then F(X+h) - F(X) / h

= 3(X+h)^2 - 3x^2 / h

= 3(x^2 + 2hx + h^2) - 3x^2 / h

= 3x^2 + 6hx +3h^2 - 3x^2 / h

= 6hx + 3h^2 / h

= h (6x +3h) / h

= 6x + 3h

I hope this answer is correct

Sam paid $8.28 for 18 stamps. At this rate, how much would it cost sam to buy 12 stamps?

Korolek [52]

First we want to find how much it costs for 1 stamp, so we do 8.28 divided by 18, which equals 0.46. Then, we multiply 0.46 and 12, which is 5.52. Therefore, it would cost $5.52 to buy 12 stamps.

Here’s a graph of a linear function. Write the equation that describes that function ??

PIT_PIT [208]

Answer:

The equation of the line is y = x + 1

Step-by-step explanation:

In order to find this, start with two points that are on the line. We'll use (0, 1) and (1, 2). Now we can use the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - 1)/(1 - 0)

m = 1/1

m = 1

Now that we have this, we can use that slope and a point in point-slope form. Then we solve for y to get the equation.

y - y1 = m(x - x1)

y - 1 = 1(x - 0)

y - 1 = 1x

y = 1x + 1

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80° mo

trasher [3.6K]

Answer:

The measure of the first angle is 50°.

Step-by-step explanation:

Let the three angles be a, b, and c.

The measure of the first angle is twice the measure of the second angle. In other words:

$a=2b$

The measure of the third angle is 80° more than the measure of the second angle. In other words:

$c=b+80$

And since the interior angles of a triangle must equal 180°:

$a+b+c=180$

Substitute a and c:

$(2b)+b+(b+80)=180$

Combine like terms:

$4b+80=180$

Subtract 80 from both sides:

$4b=100$

And divide both sides by four:

$b=25^\circ$

So, the measure of the second angle is 25°.

Since the measure of the first is twice the second, the measure of the first angle is 50°.

(And since the measure of the third is 80° than the second, the measure of the third angle is 105°.)

If AC = 52, AB = 8x + 8, and BC = 2x + 4, then the length BC is

Reil [10]

Answer:

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

52 = 8X + 8 + 2X + 4

Combining like terms:

52 = 10X + 12

Subtract 12 from both sides:

40 = 10X

Divide by 10:

X = 4

Now that we know X, we can figure out BC

BC = 2(4) + 4

BC = 8 + 4

BC = 12

Therefore BC is 12.
