Combine the following sets of terms. (2x² + 6x + 10) + (4x² + 2x + 3) show

(2x² + 6x + 10) + (4x² + 2x + 3)

Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-

= 2x^2 + 4x^2 + 6x + 2x + 10 + 3

= 6x^2 + 8x + 13   answer

(2x^2+6x+10)+(4x^2+2x+3)

2x²+4x² is 6x²

6x+2x is 8x

10+3 is 13

Answer is 6x²+8x+13

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
