Answer:

-7 < x

Name 2 values

0 and 10

Any number greater than -7 will work

Step-by-step explanation:

-4 < 2(x + 5)

Divide each side by 2

-4/2 < 2/2(x + 5)

-2 < (x + 5)

Subtract 5 from each side

-2-5 < x+5-5

-7 < x

Name 2 values

0 and 10

Any number greater than -7 will work

Answer:

The expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

Step-by-step explanation:

As we know that the area of a rectangle can be obtained by multiplying the length by the width.

i.e.

$A=l\times w$

Given

The length of a rectangle ABCD = $l$ = $(x+5) + (3x) + (4x-9)$

The width of a rectangle = $w$ = $2x$

so the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=l\times w$

$A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]$

$=\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)$

$=\left(x+5+3x+4x-9\right)\times \:2x$

$=2x\left(8x-4\right)$

$=16x^2-8x$

Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:

$A=16x^2-8x$

Hence, the 2nd option is correct.

Given: m || n and p is a transversal

Blababa [14]

Answer:

Option 3: transitive property

Step-by-step explanation:

The previous statements are

2. ∠2 ≅ ∠3 ⇒ 2. ver. ∠s theorem

And

5. m∠3 = m∠7 ⇒ 5. def. of congruent

So, The previous proved statement to make use of the transitive property reason or proof

∴ 6. m∠2 = m∠7 ⇒ 6. transitive property

Note: the transitive property states that: If a = b and b = c, then a = c.
