It's saying that the polynomial can be factored into a perfect square (x + 5)(x+5) because when you multiply it, you get x² + 5x + 5x + 25 or x² + 10x + 25 so the factored form can be rewritten as (x + 5)² because it can be multiplied by itself to get the polynomial listed, so a = x and b = 5

Find the equation of the line that contains the point (3,9) and is parallel to the line y=4x+1. Write the line in slope-intercep

Aleksandr-060686 [28]

Y = 4x + 1....slope here is 4. A parallel line will have the same slope

y = mx + b
slope(m) = 4
(3,9)...x = 3 and y = 9
now we sub and find b, the y int
9 = 4(3) + b
9 = 12 + b
9 - 12 = b
-3 = b

so ur parallel equation is : y = 4x - 3

The sides of a triangle are x, x+7, and 2x-8. If the perimeter of the triangle is 47, what is x

kirza4 [7]

just like the previous one, we sum the sides to get the perimeter.

$\bf (x)+(x+7)+(2x-8)=47\implies 4x-1=47\implies 4x=48\\\\\\x=\cfrac{48}{4}\implies x=12$
