Answer:
let the width be x inches
then the length would be 3x inches
perimeter of rectangle = p = 2(l+b)
100= 2(3x+x)
100= 2(4x)
100=8x
x=100/8
x=12.5 inches
thw width is 12.5 inches and length is 3*12.5=37.5 inches
Step-by-step explanation:
Answer:
6.3 feet
Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
a² + 3² = 7²
a² + 9 = 49
Subtract 9 from both side
a² = 40
Take the square root of both sides
a = 6.324555320336759
Rounded
a = 6.3
The answer is 6(x^2 -1) I have provided a picture with my work and the answer

Answer:
\frac{13+\left(-3\right)^2+4\left(-3\right)+1-\left[-10-\left(-6\right)\right]}{\left[4+5\right]\div \left[4^2\:−\:3^2\left(4−3\right)−8\right]+12}
Step-by-step explanation:
\frac{13+\left(-3\right)^2+4\left(-3\right)+1-\left(-10-\left(-6\right)\right)}{\frac{4+5}{\left(4^2-3^2\left(4-3\right)-8\right)+12}}
