1. the perimeter of a square is always 4 * side, so = 4*31/8 = 31/2 or 15 and 1/2
2. area of a square is always the side multiplied by each other, so: 9/2 * 9/2 = 81/4 or 20 and 1/4

(2a^2b + 3ab^2 - b^3) - (4b^3 - 3ab^2 -6a^2b)

<em>Hi there!</em>

<em>~</em>

<em></em> $(2a^2b+3ab^2-b^3)-(4b^3-3ab^2-6a^2b)$ <em></em>

<em>Distribute the Negative Sign:</em>

<em></em> $= 2a^2 b + 3ab^2 - b^3 + -1(4b^3 - 3ab^2 - 6a^2b)\\= 2a^2 b + 3ab^2 + - b^3 + -1 (4b^3) + -1 (-3ab^2) + -1 (-6a^2b)\\= 2a^2 b + 3ab^2 + -b^3 + -4b^3 + 3ab^2 + 6a^2 b$ <em></em>

<em>Combine Like Terms:</em>

<em></em> $= 2a^2 b + 3ab^2 - b^3 + -4ab^3 + 3ab^2 + 6a^2 b\\= (2a^2 b + 6a^2 b) + ( 3ab^2 + 3ab^2) + (-b^3 + -4b^3) \\= 8a^2 b + 6ab^2 + -5b^3$ <em></em>

<em>Answer : </em> $8a^2 b + 6ab^2 + -5b^3$ <em></em>

<em>Hope this helped you!</em>

The formula y - y1 = m(x - x1) is the point-slope form of the equation of a line where m is the slope of the line and (x, y) and

a_sh-v [17]

Answer:

The slope of a line that includes the points (4, -2) and (5, 0) is 2

Step-by-step explanation:

You know that the formula y - y1 = m(x - x1) is the point-slope form of the equation of a line where m is the slope of a line.

The line must include the points (4, -2) and (5, 0). So, being:

(x,y)= (4,-2)
(x1,y1)= (5, 0)

and replacing in the point-slope form of the equation of a line:

-2-0=m(4-5)

You solve the equation for m and get:

-2=m*(-1)

$m=\frac{-2}{-1}$

m=2
