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.

Suppose that a rectangle has an area of 54 square meters. Express the perimeter P as a function of the length x of one of the si

Lapatulllka [165]

Answer:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Step-by-step explanation:

The area of the rectangle can be written as:

$A = x*h$

here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.

$54 = x*h$

The perimeter of a rectangle can be written as:

$P = 2x+2h$

To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.

$54 = x*h$

$h=\dfrac{54}{x}$

now we can substitute this 'h' into our equation of the perimeter.

$P = 2x+2\left(\dfrac{54}{x}\right)$

$P = 2\left(x+\dfrac{54}{x}\right)$

and voila! we have expressed P in terms of x only.

this can be written as P as a function of x as:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Write the equation of a circle with a center at (2.5, –3.5) and a diameter of 12.

Paul [167]

Answer:

second option

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus

(x - 2.5)² + (y - (- 3.5))² = 6², that is

(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
