Which expression represents the area of the rectangle (2x+7)(4x+5)?

zhenek [66]

So we'll do FOIL (first, outer, inner, last)

The equation is (4x+5)(2x+7)

First, 4x·2x=8x²

Outer, 4x·7=28x

Inner, 5·2x=10x

Last, 5·7=35

Add like terms and you get:

8x²+38x+35

Solve for C when 9=c(c-8) Can you show your work too? This question confuses me!

Marrrta [24]

9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9

In short, Your Answers would be -1 and 9

Hope this helps!

Given the functions ƒ(x) and g(x), which of the following statements is true? x -2 -1 0 1 2 ƒ(x) -3 3 5 3 -3 g(x) = -x2 + 4x ƒ(x

Morgarella [4.7K]

Answer:

The correct option is 1.

Step-by-step explanation:

From the given table is notices that the function f(x) is a downward parabola.

The maximum value of f(x) is 5 at x=1.

The function g(x) is

$g(x)=-x^2+4x$

vertex of the parabola is

$(\frac{-b}{2a}, g(\frac{-b}{2a}))$

$(\frac{-4}{2\times 1}, g(\frac{-4}{2\times 1})$

$(2, g(2))$

Put x=2.

$g(x)=-2^2+4(2)=4$

Therefore the vertex of g(x) is (2,4). The vertex of a downward parabola is the maximum point of the function.

Therefore ƒ(x) has the greater maximum. Option 1 is correct.
