Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
Answer:
$44
Step-by-step explanation:
Use formula
% out of 100/100% = part/whole
20%/100 = 12/16+x
Cross multiply
(12)(100) = (20)(16+x)
1200=320+20x
Solve for x
1200-320 = 20x
880 = 20x
880/20 = x
44 = x

Answer:
<h2>-x²+4x +6</h2>
Step-by-step explanation:
Given f(x)=4x+1 and g(x)=x²-5
(f-g)(x) is derived by taking the difference of both functions
(f-g)(x) = f(x)-g(x)
(f-g)(x) = 4x+1 - (x²-5)
(f-g)(x) = 4x+1-x²+5
(f-g)(x) = -x²+4x +6
This gives the requires expression
12.56 cubic inches
Step-by-step explanation:
Volume of a cone= π r² h/3
3.14*2*2*3/3
3.14*4*3/3
12.56*3/3
=12.56 cubic inches
Answer:
n=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11−8n=1−3n
11+−8n=1+−3n
−8n+11=−3n+1
Step 2: Add 3n to both sides.
−8n+11+3n=−3n+1+3n
−5n+11=1
Step 3: Subtract 11 from both sides.
−5n+11−11=1−11
−5n=−10
Step 4: Divide both sides by -5.
−5n
−5
=
−10
−5
n=2
