step 2. s = (a + b + c)/2 = (3 + 5 + 6)/2 = 7
step 3. A = sqrt(7(7-4)(7-5)(7-6))
step 4. A = sqrt(7(3)(2)(1))
step 5. A = sqrt(42)
step 6. A = 6.4807 = 6.5cm^2.

The length of a rectangle is 3 inches less than three times its width. The perimeter of the rectangle is 34 inches. Find the dimensions of the rectangle
Answers
Given:
The length of a rectangle is 3 inches less than three times its width.
The perimeter of the rectangle is 34 inches.
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then, the length of a rectangle is 3 inches less than three times its width.
Length of the rectangle = 3x-3
Now, perimeter of the rectangle is
[tex]Perimeter=2(Length + Width)[/tex]
[tex]Perimeter=2(3x-3+x)[/tex]
The perimeter of the rectangle is 34 inches.
[tex]34=2(4x-3)[/tex]
[tex]34=8x-6[/tex]
[tex]34+6=8x[/tex]
[tex]40=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{40}{8}=x[/tex]
[tex]5=x[/tex]
The value of x is 5. So, width of the rectangle is 5 inches.
[tex]Length=3x-3[/tex]
[tex]Length=3(5)-3[/tex]
[tex]Length=15-3[/tex]
[tex]Length=12[/tex]
Therefore, the length of the rectangle is 12 inches and the width of the rectangle is 5 inches.
Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2
Answers
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation
[tex]4\left(n\right)-3=-2\left(n\right)+9[/tex]
remove the parentheses
[tex]4n-3=-2n+9[/tex]
Add 3 to both sides
[tex]4n-3+3=-2n+9+3[/tex]
Simplify
[tex]4n=-2n+12[/tex]
Add 2n to both sides
[tex]4n+2n=-2n+12+2n[/tex]
Simplify
[tex]6n=12[/tex]
Divide both sides by 6
[tex]\frac{6n}{6}=\frac{12}{6}[/tex]
Simplify
[tex]n=2[/tex]
Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2

Can someone please help me understand how to expand 8(3y-4). Please give a detailed explanation.
Answers
Answer:
24y - 32
Step-by-step explanation:
You take the 8 and multiply each term by in the parentheses by 8, so
8(3y - 4) becomes 8 * 3y - 8 * 4 = 24y - 32
Answer:
well, you can multiply them, to simplify the equation, but to expand, try adding or multiplying 2 multiples of 8, in the middle the 4 can change by adding 2+2 or 3+1. For 3y, you can do 3*y.
