Answer:

B.) False

Step-by-step explanation:

A regular tessellation is a pattern made by repeating a regular polygon. But in this image, it is a demiregular tessellations. Demiregular tessellations are a set of tessellations made from 2 or more regular polygon faces.

Hope this helps you out! : )

Simplify the sum. d^2-7d+12/d^2-d-6 + d^2+5d+6/d^2-2d-15

Law Incorporation [45]

Answer:

The sum is $\frac{2d^2-5d+24}{d^2-3d-10}$

Step-by-step explanation:

The given expression is

$\frac{d^2-7d+12}{d^2-d-6}+\frac{d^2+5d+6}{d^2-2d-15}$

These are all quadratic trinomials, so we split each of the middle terms to obtain,

$\frac{d^2-4d-3d+12}{d^2-3d+2d-6}+\frac{d^2+2d+3d+6}{d^2-5d+3d-15}$

We factor to obtain,

$\frac{d(d-4)-3(d-4)}{d(d-3)+2(d-3)}+\frac{d(d+2)+3(d+2)}{d(d-5)+3(d-5)}$

We factor further to obtain,

$\frac{(d-4)(d-3)}{(d-3)(d+2)}+\frac{(d+2)(d+3)}{(d-5)(d+3)}$

We cancel out the common factors to get,

$\frac{(d-4)}{(d+2)}+\frac{(d+2)}{(d-5)}$

The least common denominator is $(d+2)(d-5)$ .

We collect LCD to get

$\frac{(d-4)(d-5)+(d+2)(d+2)}{(d+2)(d-5)}$

We now expand to get,

$\frac{d^2-5d-4d+20+d^2+2d+2d+4}{d^2-5d+2d-10}$

We simplify to get,

$\frac{d^2-9d+20+d^2+4d+4}{d^2-3d-10}$

We simplify further to get,

$\frac{2d^2-5d+24}{d^2-3d-10}$

Find function then simplify tje answer

Scrat [10]

Answer:

a)(x+h+2)²=x²+2xh+h²+4x+4h+2

b)(x+h+2)²–(x+2)²=2xh+h²+4h

c)2x+4+h

Step-by-step explanation:

f(x)=x²+4x+2

Aight so for part a you have to replace x with x+h

a)f(x+h)=(x+h)²+4(x+h)+2=x²+2xh+h²+4x+4h+2

and then for part b you need to subtract f(x) from part a:

b)f(x+h)–f(x)=x²+2xh+h²+4x+4h+2–x²–4x–2===>

2xh+h²+4h

and for part c divide the answer by h:

$\frac{f(x + h) - f(x)}{h} = = = > \\ \frac{2xh + 4h + {h}^{2} }{h} = = = > \\ 2x + 4 + h$

and if you limit h by 0 you'll get the derivative of f(x)

What does the word consecutive mean

Nesterboy [21]

It means coming right after the other

example, consecutive integers are like 1,2,3,4,5, etc

consecutive even integers are 2,4,6,8 etc

consecutive odd integers are 1,3,5,7, etc

you get the point
