A Which is the correct reason why (2 + y)2 is not equal to x² + y²,
The expression
22
+y? is the product of two factors
(x+y)(x + y), and (x + y)2 is the sum of two terms.
The expression x2 + y² is the product of two factors
(x + y)(x + y) and (x + y)2 is the product of two terms,
B
The expression (2 + y)2 is the product of two factors
(x + y) (2 + y) and 2? + yº is the sum of two terms.
The expression (2 + y)2 is the product of two factors
(2 + y) (x + y), and x² + y² is the product of two terms.

p> q if you calculate p is100 q is 79

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
