Expand, answer should be a polynomial in standard form

(5a+2)(a+4)=

The standard form of the expression (5a+2)(a+4) is .

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

=

=  

or,  

Also,  Standard Quadratic form is

Hence, the standard form of (5a+2)(a+4) is .

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

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)
