Answer:
n=9
Step-by-step explanation:
You use reverse PEMDAS.
First you would divide by 3 on both sides. This should give you:
n²=81
Then you would find [tex]\sqrt{81}[/tex]. Which is 9.

5) Solve: 2.4p + 6 = 48
Answer:
p = 17.5
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate x
2) To isolate x, first -6 from +6 and 48
+6 - 6 = 0
48 - 6 = 42
Equation: 2.4p = 42
3) Now we are left with 2.4p = 42
4) Next, divide 2.4 from 2.4 and 42
2.4/2.4 = 0
42/2.4 = 17.5
5) We are left with
p = 17.5
Therefore, the answer is p = 17.5
Hope this helps!

A golf course charges $18 to golf 18 holes and $7 for a cart for a no-member.
To become a member you have to pay $560 and $5 for a cart for each round
of 18 holes you golf. How many times would you have to golf 18 holes with a
cart to justify becoming a member?
*
Answer:
at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..

A triangle has an area of 49.5cm2 If the base of the triangle is 9cm. What is the height of the triangle A = 1/2BH
Answer: 11
Step-by-step explanation:
49.5/9 = 5.5
5.5 x 2 =11
11x9=99
99/2=49.5
7n2 + 5 = 453
Solve the quadratic function
7n^2 + 5 = 453
Subtract 5 from both sides:
7n^2 = 448
Divide both sides by 7:
N^2 = 64
Take the square root of both sides:
N = 8

Find the area and perimeter of a rectangle if the length is (x+7) and the width is (x+3).
[tex]\sf Length\:=\:(x+7) \\\\\sf
Breadth\:=\:(x+3) \\\\\sf
Area= Length\: x\: Breadth \\\\\sf
=(x+3)(x+7) \\\\\sf
=x^2+7x+3x+21 \\\\\sf
=x^2+10x+21 \\\\\sf
\boxed{Area=x^2+10x+21} \\\\ \\\\\sf
Now, \:Perimeter\:=\: 2x(length +breadth) \\\\\sf

\boxed{Perimeter=4x+20} [/tex]
[tex]l = (x + 3) \\ b = (x + 7)[/tex]
Area:
[tex] = l \times b \\ = (x + 3)(x + 7) \\ = x(x + 7) + 3(x + 7) \\ = {x}^{2} + 7x + 3x + 21 \\ = {x}^{2} + 10x + 21[/tex]
Perimeter:
[tex] = 2(l + b) \\ = 2((x + 3) + (x + 7)) \\ = 2(x + 3 + x + 7) \\ = 2(2x + 10) \\ = 4x + 20[/tex]

A square has an area of 200 square feet. Between what two consecutive integers would the
length of each side fall?
HELP ME PLEASE
Answer:
14 & 15
Step-by-step explanation:
The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].
So we take [tex]s = \sqrt{200} = 14.14[/tex]
And this is between the integers 14 and 15.
