tiles of patterns is shown below. Consider function that represents the number of whithe in each figure.Figure 1Figure 2Figure 3Figure 4Select all statements that are true.

Answers

Answer 1

Answer: Call n the number of figure and w the number of white figures:

w = (n+2)^2 - n^2

w = n^2 + 4n + 4 - n^2 = 4n + 4

w = 4 (n+1)

All those formulas are equivalent.

Thank you.

Answers

4x+32=8+6x
Subtract 4x from both sides.
32 = 8 + 2x
Subtract 8 from both sides.
24 = 2x
Divide 2 to both sides
x = 12

4x+32=8+6x
4x+32-4x=8+6x-4x
32=8+2x
32-8=8+2x-8
24=2x
Divide each side by 2.

use a protractor to draw an angle of 55 degree that opens from the left.then draw an angle of 125 degree that opens from the right .how do the angles apper to be related?

Answers

You should first draw a strait line across your paper. Draw the 55 degree angle with your protractor. Then draw the 125 degree angle it should stop at where the line of the 55 degree angle you just drew. These two angles add up to 180 degrees. 125+55 = 180. These are known as supplementary angles.

Which algebraic expression is equivalent to the expression below?15(9 + 5x) + 16

75x - 151
75x + 151
75x + 119
5x + 151

Answers

so first distibute using distributive porperty

distributive property=
a(b+c)=ab+ac

so 15(9+5x)=135+75x

135+75x+16
group like terms
75x+151

the answer is the second option

Simplify:
15 (5x+9)+16

15 (5x+9) = 75x+135:
75x+135+16

75x+(135+16) = 75x + 151
Answer = 75x + 151

51) Rewrite the formula for the circumference of a circle C=2 /pi "r" in terms of its diameter "d". Please show your working :)

Answers

The circumference of a circle=2 $\pi$ r
We know that diameter is double the radius, and therefore can be written as d=2r
Circumference of a circle in terms of diameter is C= $\pi$ d
The 2r cancels out
