Answer:
b = -9
Step-by-step explanation:
1. Move the variables to the left side. Be sure to change the terms (add/subtract)
-9b-6 = -3b+48
-9b+3b-6 = 48
2. Combine like terms.
-9b+3b-6 = 48
-6b = 48 + 6
3. Divide both sides by -6.
-6b = 54
b = -9
Answer:
Below
Step-by-step explanation:
The length of this triangle is 3x+1 and the width is x.
The perimeter P is:
P= 2(3x+1)+2*x
P= 6x+2+2x
P= 8x+2
Let's evaluate it when x=1/2
●1/2 =0.5
P= 8*0.5+2 =4+2= 6 ft
●●●●●●●●●●●●●●●●●●●●●●●●
The area A is:
A = (3x+1)*x
A= 3x^2 +x
Let's evaluate it when x=0.5 feet
A= 3*0.5^2 +0.5
A= 3*0.25+0.5
A= 0.75 +0.5
A= 1.25 ft^2
45.2216762184
It is the square root of
405x5
