$\mathbb{ANSWER:}\downarrow$

$\mathrm{4(2x+5y)}$

$\textsc{Explanation\::}$

Use the GCF to factor this expression .

The GCF stands for :

$\pmb{G}$ stands for Greatest

$\pmb{C}$ stands for Common

$\pmb{F}$ stands for Factor

$\pmb{GCF}$ = Greatest Common Factor

The abbreviation GCF comes in handy when it comes to factoring expressions like 8x+20y ( :

The Greatest Common Factor of 8x+20y is 4 , so that's what we factor out :

4(2x+5y)

Hint : Enter 4 , then 2 , then 5)

If an equation has two roots -4 and 7, what could be the quadratic equation?

aleksklad [387]

Answer:

f(x) = x^2 - 3x - 28

Step-by-step explanation:

The root -4 corresponds to the factor (x + 4); the root 7 corresponds to (x - 7). The equation is thus f(x) = (x + 4)(x - 7) = x^2 - 3x - 28, or

f(x) = x^2 - 3x - 28

Give a third degree polynomial that has zeros of 13, 5i, and −5i, and has a value of −680 when x=3. Write the polynomial in stan

Vikki [24]

Answer:

$\dfrac{17x^3-221x^2+425x-5525}{9}\\$

Step-by-step explanation:

hello

we need to find something like, a being real

$a(x-13)(x-5i)(x+5i)$

with a so that

$a(3-13)(3-5i)(3+5i)=-680\\\\a(-10)(3^2-(5i)^2)= -10(9+25)a=-360a=-680\\ a = \dfrac{680}{360}=\dfrac{17*40}{9*40}=\dfrac{17}{9}$

so the third degree polynomial that we are looking for is

$\dfrac{17}{9}(x-13)(x-5i)(x+5i)\\=\dfrac{17}{9}(x-13)(x^2+25)\\\\=\dfrac{17}{9}(x^3+25x-13x^2-13*25)\\\\\\=\dfrac{17}{9}(x^3-13x^2+25x-325)\\\\\\\\=\dfrac{17}{9}x^3-\dfrac{17*13}{9}x^2+\dfrac{17*25}{9}x-\dfrac{17*325}{9}\\=\dfrac{17}{9}x^3-\dfrac{221}{9}x^2+\dfrac{425}{9}x-\dfrac{5525}{9}\\$

hope this helps

A basketball player claims to make 47% of her shots from the field. We want to simulate the player taking sets of 10 shots, assu

Molodets [167]

Answer:

0.9 or 90%

Step-by-step explanation:

The probability of shot is 47%

The probability of no shot is 100 -47 = 53%

The dot plot is made from the 10 repeated shots which recorded 25 scores.

The number of dots on the fifth tick is 9 of 10 shots

therefore; 9/10 = 0.9, which 90 in percentage.
