Answer:

7√2 / 2

Step-by-step explanation:

An isosceles right triangle is also known as a 45-45-90 triangle.  For such a triangle, the hypotenuse (long side) is √2 the legs.

s√2 = 7

s = 7/√2

s = 7√2 / 2

You can also show this with Pythagorean theorem.

The sum of the perimeters of 2 different squares is 68 feet, and the difference between their perimeters is 12 feet. What is the
True [87]

9514 1404 393

Answer:

  • 10 ft
  • 7 ft

Step-by-step explanation:

The side lengths are 1/4 of the perimeter, so we can say ...

  the sum of side lengths is 68 ft/4 = 17 ft

  the difference of side lengths is 12 ft/4 = 3 ft

Using x to represent the side length of the smaller square, we have ...

  x + (x +3) = 17 . . . . . . the larger square has side length x+3

  2x = 14 . . . . . . . . . subtract 3

  x = 7 . . . . . . . . divide by 2

The side lengths of the squares are 7 feet and 10 feet.

If x=2y=4z, express
Umnica [9.8K]
x = 4z

2y = 4z

Dividing both sides by two,

y = 2z

OK, part 1.

x+4y+z = 4z + 4(2z) +z = 13z

When z=2 then x+4y+z =13(2)=26

Part 2.

2x+3y+2z= 2(4z) +3(2z) + 2z = 16z

When z=2 then 2x+3y+2z=16(2)=32
