You would use distribution

The answer is
50w^7 + 40w^4 - 20w^2

The first step for solving this expression is to multiply each term in the parenthesis by 10w.
10w × 5 $w^{6}$ + 10w × 4w³ - 10w × 2w
Calculate the product of 10w × 5 $w^{6}$
50 $w^{7}$ + 10w × 4w³ - 10w × 2w
Calculate the product of 10w × 4w³
50 $w^{7}$ + 40 $w^{4}$ - 10w × 2w
Lastly,, calculate the final product of -10w × 2w
50 $w^{7}$ + 40 $w^{4}$ - 20w²
Since you cannot simplify any further,, the correct answer to your question will be 50 $w^{7}$ + 40 $w^{4}$ - 20w².
Let me know if you have any further questions

Point A(2, 2) and point D(−4, −3) are located on the grid. Which measurement is closest to the distance between point A and poin

Virty [35]

Answer:

Step-by-step explanation:

The distance formula is $D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}}$

Where $(x_1,y_1)$ is the first coordinate (our case, point A(2,2)) & $(x_2,y_2)$ is the second coordinate (our case, point D(-4,-3))

Plugging these in into the formula gives us:

$D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}} \\D=\sqrt{(-3-2)^{2}+(-4-2))^{2}} \\D=\sqrt{(-5)^{2}+(-6)^{2}}\\ D=\sqrt{25+36} \\D=\sqrt{61} \\D=7.81$

Answer choice B is closest.

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 + 3x = 24

Sophie [7]

We have that
x² + 3x = 24
Group terms that contain the same variable
(x² + 3x) = 24
Complete the square. Remember to balance the equation by adding the same constants to each side
(x² + 3x+2.25) = 24+2.25

Rewrite as perfect squares

(x+1.5)² = 26.25
(+/-)[x+1.5]=5.12
(+)[x+1.5]=5.12----> x=5.12-1.5---> x=3.62
(-)[x+1.5]=5.12-----> x=-1.5-5.12---> x=-6.62

the answer is
3.62, –6.62
