Answer:

Step-by-step explanation:

1. (2x-4)^2 = (2x-4)(2x - 4) Expand:

2. 4x^2 - 16x + 16

so the coefficient of the second term is 16.

Answer:

-16.

Step-by-step explanation:

(2x–4)^2

= (2x - 4)(2x - 4)

= 4x^2 - 8x - 8x + 16

= 4x^2 - 16x + 16

Let's apply BPT theorem(Not necessary we can apply common ratios and similarities)

AB/BC=CE/DE

Put values

15/9=6/x

Option B

Let's solve it out

15x=54
x=54)15
x=18/5
x=3.6

Find the preimage of the point (4, 3) under the given transformation. A transformation T : (x, y) (x - 2, y + 3) (2, 6) (2, 3) (

Mashcka [7]

Answer:

The preimage is $(6,0)$

Step-by-step explanation:

The given point is (4,3).

The translation rule is

$T:(x,y)\rightarrow (x-2,y+3)$

Let $(a,b)$ be the preimage.

Then,

We apply this rule to the preimage to obtain;

$T:(a,b)\rightarrow (a-2,b+3)$

This implies that;

$a-2=4$

$\Rightarrow a=4+2$

$\Rightarrow a=6$

Also,

$b+3=3$

$\Rightarrow b=3-3$

$\Rightarrow b=0$

Hence the preimage is $(6,0)$
