The area would be (x+3) (4x-1) which is 4x^2 +11x -3. The perimeter is 2(x+3) plus 2(4x-1) which is 2x +6 plus 8x-2 which is 10x +4. If x=7 then the perimeter is 74 ft.
Answer: x = 18
Step-by-step explanation:
First, since both angles shown are equal to each other, you can immediately set your equation.
5x + 5 = 95
Next, move 5 to the opposite side of the equation to isolate your x value (5x). This step is simply subtracting the hanging 5.
5x + 5 (-5) = 95 (-5)
5x = 90
Finally, you need to divide both sides of the equation by 5 (the 5 next to the x) to *fully* isolate the x value.
5x / 5 = 90 / 5
x = 18
final answer: x = 18
Hopefully this helps with the remainder of your lesson! :)
The square root of 100 is 10. The drawing must be 10 cm by 10 cm.
1 cm = 2 ft, so 10 cm must equal 20 feet.
20 * 20 = 400 square feet

Answer:
31.5
Step-by-step explanation:
so if they say that every inch is realy 18 ft and u have 1.75 inches then multiply 8 by 1.75 to get the width of the stage
