Answer:

20%

Step-by-step explanation:

First, I added them up. From the things we know, blue, red, green, yellow combined equals 16 marbles. 20-16 equals 4. So there are 4 white marbles. 4/20 times 5 equals 20/100. So the percent of the marbles that are white is 20%.

10 points! How do I factor 8x^2-26x+15

Rufina [12.5K]

The AC method, also known as splitting the middle, can be shown like this:

8x^2 - 26x + 15

Check factors of 120.

1 * 120

-1 * -120

2 * 60

-2 * -60

3 * 40

-3 * -40

5 * 24

-5 * -24

6 * 20

-6 * -20 (these factors, when added together, are equal to the middle term, and thus splitting the middle term is possible.)

Split the middle term.

8x^2 - 6x - 20x + 15

Group in terms of 2.

(8x^2 - 6x) - (20x + 15)

Factor each binomial.

2x(4x - 3) - 5(4x - 3)

Rearrange the terms.

(2x - 5)(4x - 3)

Please answer I will mark u brainliest or wtv its called

Lelu [443]

Answer:

B) 10 cm

Step-by-step explanation:

Hello!

We can use the Pythagorean theorem to solve for the hypotenuse.

Formula: $a^2 + b^2 = c^2$

a = leg
b = leg
c = hypotenuse

We can plug in the values for each leg to solve for the hypotenuse.

<h3>Solve for c</h3>

$a^2 + b^2 = c^2$
$6^2 + 8^2 = c^2$
$36 + 64 = c^2$
$100 = c^2$
$\sqrt{100} = \sqrt{c^2}$
$10 = c$

The answer is Option B: 10 cm

Perform the requested operation or operations.

$f(x) = \frac{x-3}{5}$
$g(x) = 5x+3$
$g(f(x)) = 5(\frac{x-3}{5})+3 = x-3+3 = x$

EDIT:
$f(g(x))=\frac{(5x+3)-3}{5}=\frac{5x+0}{5}=\frac{5x}{5}=x$
