Answer:

Step-by-step explanation:

For b, the constant term is 3, not -3. B is incorrect.

For c, when the brackets are removed using foil, -3 * - 3 = 9. C is incorrect.

For d, There is no reduction, alteration or math procedure that you can use that will make the constant term anything but 9. The answer is not D.

======================

That means you are left with A which must be right or the question isn't. Turns our that A is the answer -3 * 1 = - 3

A triangle has a perimeter of 165cm the first side is 65 cm less than twice the second side the third side is 10 cm less than th

katrin2010 [14]

Answer:

The sides of the triangle are:

Second side = 60 cm

First side = 55 cm

Third side = 50 cm

The perimeter equation can be given as:

$4s-75=165$

Step-by-step explanation:

Given:

Perimeter of triangle = 165 cm

First side = 65 cm less than twice the second side

Third side = 10 cm less than the second side

To find length of each side and write the equation that represents the perimeter of triangle.

Solution:

Let length of second side be = $s$ cm

First side will be given as = $(2s-65)$ cm

Third side will be given as = $(s-10)$ cm

Perimeter of triangle = Sum of all sides

Thus, perimeter can be given as:

⇒ $First\ side+ Second\ side+Third\ side$

⇒ $2s-65+s+s-10$

Simplifying by combining like terms.

⇒ $4s-75$

We know the perimeter of triangle = 165 cm

So, the perimeter equation can be given as:

$4s-75=165$

Solving for $s$ .

Adding 75 both sides.

$4s-75+75=165+75$

$4s=240$

Dividing both sides by 4.

$\frac{4s}{4}=\frac{240}{4}$

$s=60$

Thus, the sides of the triangle are:

Second side = 60 cm

First side = $2(60)-65$ = 55 cm

Third side = $60-10$ = 50 cm

What value of X makes this equation true?

Studentka2010 [4]

Answer:

The answer is B

Step-by-step explanation:

-53=8x+5

First you would subtract the 5 on both sides then you would end up with

-58=8x

then you would divide both sides by 8 and get 7.25 or 7 1/4
