If f(x) = 2x + 5x and g(x) = 3x - 5, find (f+ g)(x).

Papessa [141]

Answer:

D. 10x - 5

General Formulas and Concepts:

Algebra I

Terms/Coefficients/Degrees

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 5x

g(x) = 3x - 5

(f + g)(x) is f(x) + g(x)

Step 2: Simplify

f(x) = 7x

g(x) = 3x - 5

Step 3: Find

Substitute: (f + g)(x) = 7x + (3x - 5)
Combine like terms: (f + g)(x) = 10x - 5

Answer:

-1

Step-by-step explanation:

$=(\frac{1}{\sqrt{2}}(1+i))^4\\=\frac{1}{4}(1+i)^2(i+i)^2\\=\frac{1}{4}(2i)(2i)\\=i^2\\=-1$

The perimeter of ABCD is 66 and DC is twice as long as CB how long is a B

Natali5045456 [20]

Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x
6x = 66
x = 11
Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x
6x = 66
x = 11
