Algebra tiles to prove that 4 + 8x and 4(2x+1)

Answers

Answer 1

Answer: not sure what algebra tiles are

not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x

remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x

Answer 2

Answer: 4 + 8x

Now, see if the simplified form of 4(2x + 1) is equal to that.

4*2x = 8x
4*1 = 4

4 + 8x = 4 + 8x Correct

Quadrilateral M N O P was dilated with the origin as the center of dilation to create quadrilateral ′′′′ M ′ N ′ O ′ P ′ . The quadrilateral was dilated using a scale factor of 1.5 1 . 5 . The coordinates of the vertices of quadrilateral M N O P are given. What are the coordinates of ′ N ′ ?

Answers

The co-ordinates of N' will be (1.5c,1.5d).

What is a quadrilateral ?

A quadrilateral is a 2D figure having four sides.

According to the given question a quadrilateral M N O P was dilated with the origin as the center of dilation to create quadrilateral M ′ N ′ O ′ P ′.

The quadrilateral was dilated using a scale factor of 1.5.

Assuming the given co-ordinates of the quadrilateral are (a,b), (c,d), (e,f), (g,h).

It is dilated by a factor of 1.5 with origin as the center of dilation we can think of these given vertices of the quadrilateral as straight lines from origin so after the dilation each line will be stretched by a factor of 1.5.

∴ The dilated co-ordinates will be multiplied by a factor of 1.5 and they will be

(1.5a,1.5b), (1.5c,1.5d), (1.5e,1.5f), (1.5g,1.5h).
