The length of a rectangle is represented by the function l(x) = 4. the width of that same rectangle is represented by the function w(x) = 7x^2-4x+2. which of the following shows the area of the rectangle in terms of x?

28x^2 -16x + 8

Step-by-step explanation:

The area is calculated multiplying the length by the width. So,

A = 4.(7x^2 - 4x + 2) = 28x^2 - 16x + 8

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
