Answer:

p=5

Step-by-step explanation:

3p-7+p=13

Add like terms.

3p+p-7=13

4p-7=13

Add 7 to both sides.

4p-7+7=13+7

4p=20

Divide 4 from both sides.

$\frac{4p}{4}$ = $\frac{20}{4}$

p=5

Hope this helps!

If not, I am sorry.

I NEED HELP!!

Bess [88]

<h2>Answer:</h2>

4x - 6 + 2x = 3(2x - 2)

4x - 6 + 2x = 6x - 6

[ both sides - 6 cancel each other ]

4x + 2x = 6x

6x = 6x

[ both sides 6x cancel each other ]

0 = 0.

A rectangular pool is to be built on a lot that measures 20 m by 12 m. A wooden deck of uniform width, equal to the area of the

frutty [35]

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

Let

$l=\text{length of the side of the pool}\\b=\text{breadth of the pool side}\\w=\text{the width of the strip of deck surrounding the pool}$

From the question, we can build the following relationships

$l+2w=20\\b+2w=12$

subtracting to eliminate $w$ (we do not even need it!)

$l-b=8\\b=l-8$

we can also build another relationship from the question. Since the area of the strip equals the area of the pool:

$lb+lb=2lb=20\times 12\\lb=120$

We have two unknowns, $l$ and $b$ . Eliminate $b$

$lb=120\\l(l-8)=120\\l^2-8l-120=0$

If we solve the quadratic equation for $l$ , we get

$l=4+2\sqrt{34}\approx 15.7m$

and

$b=l-8\\b=(4+2\sqrt{34})-8\\b=2\sqrt{34}-4\approx7.7m$

The length and breadth(width) of the pool are

$l\approx15.7m\text{ and }b\approx7.7m$

What number should be added to both sides of the equation to complete the square? X^2+12x

Zanzabum

The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20
