A = P(1 + rt)

Divide both sides by (1 + rt):-

P = A / (1 + rt)

A

I would say A is your answer since your trying to isolate P you would divide everything by (1+rt).

Find the perimeter of a rectangle <br> L= 2x^2+3x+1<br> W= x+3
ahrayia [7]

Answer:

The perimeter of the rectangle is P(x) = (4x^{2}  + 8x + 8)

Step-by-step explanation:

Length of the rectangle  = 2x^{2}   +3x + 1

Width of the rectangle =   x + 3

The Perimeter of the Rectangle = 2 (Length + Width)

So, here the perimeter = 2((2x^{2}  + 3x +1 )+(x+3))  = 2 (2x^{2}  + 3x + 1 + x +3)\\= 2(2x^{2}  + 4x+4) = 4x^{2}  + 8x + 8

Hence,the perimeter of the rectangle is P(x) = (4x^{2}  + 8x + 8)

What is the slant height x of this square pyramid?
Inessa05 [86]
1) What is the slant height x of this square pyramid? Express your answer in radical form

sin 60=x/4--------> x=4*sin 60------> 4*(√3/2)-------> 2 √3 m

the answer Part 1) is 2 √3 m

2) The base of a regular pyramid is a hexagon. What is the area of the base of the pyramid?
[area of the base}=[area of hexagon]
[area of hexagon]=6*[area of triangle]

area of triangle
sin 60=a/14-------> a=(√3/2)*14-------> a=7√3 cm
cos 60=(b/2)/14--------> (b/2)=cos 60*14-----> (1/2)*14---------> (b/2)=7
base of triangle=2*7--------> b=14 cm

[area of triangle]=14*7√3 /2--------> 49√3 cm²
so
[area of hexagon]=6*[49√3]--------> 294√3 cm²

What is 12+24=2(6+ )
Lyrx [107]

Answer:

\huge \boxed{x=12}

Step-by-step explanation:

Let the unknown number be x.

12+24=2(6+x)

Switch sides.

2(6+x)=12+24

Expand brackets.

12+2x=12+24

Subtract 12 from both sides of the equation.

12+2x-12=12+24-12

2x=24

Divide both sides of the equation by 2.

(2x)/2=24/2

x=12
