Answer:

$32x^3+4x^2+41x-35$

Step-by-step explanation:

Given expression is,

$(4x^2+3x+7)(8x-5)$

Using the distributive property,

$(4x^2+3x+7)(8x)-(4x^2+3x+7)(5)$

Again by distributive property,

$4x^2(8x)+3x(8x)+7(8x)-4x^2(5)-3x(5)-7(5)$

$32x^3+24x^2+56x-20x^2-15x-35$

Combine like terms,

$32x^3+4x^2+41x-35$

f(4) = 1

Step-by-step explanation:

f(4) = what?

So if we know that x, aka 4, is technicially f is greater then 2, so you can plug in x as 4. So that means 5(4) - 19 = 20 - 19 = 1, so f(4) = 1

A square has an area that is less than 100m^2. What is a reasonable range for the graph of the square side?

bezimeni [28]

The area of the square is obtained by taking the square of the length of one side. Since it is said that the area of the square is less than 100 m^2, taking the square root of that where: sqrt (100) = 10, the side of that square should be less than 10 as well. Among the choices, D. 0 <y <10 (where y = length of side of square) is the correct answer.
