W=x
L=2x+17
Double everything since we need to lengths and two widths to find the perimeter
2x+17+2x+17+x+x = 76
Combine like terms
6x+34=76
Solve for x
First step is subtract 34 from both sides
6x=42
Next you divide both sides by 6 in order to get x by itself
X=7
Now you plug in 7 into the x’s in length and width
W=7 cm
L=31 cm
THE WIDTH IS 31 CM
Check:
7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.
Answer: A would be the answer
Step-by-step explanation:
Answer:
Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x 2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.
Step-by-step explanation:
We are given with a circle of center at (6,4) and that passes through (2,1). In this case, we follow the formula (x-h)^2 + (y-k)^2 = r^2.Substituting, (x-6)^2 + (y-4)^2 = r^2. at (2,1), we substitute the points: r then is equal to 5 which is the radius of the circle. The final equation of the circle is then (x-6)^2 + (y-4)^2 = 25.
1. x= 70, 2. x= 13, 3. x=9.6
