If I understood the question correctly, let's set the coordinates (5,5) from the origin (the home). To find the longer side of the triangle, (the distance between the husband and wife), we use A squared * B squared= C squared. 25*25=625, the square root of 625 is 25. So the distance between the husband and wife would be 25 miles. Therefore, one mile less than their distance would be 24 miles. To answer your question, <em><u>Juan is 24 miles from home.</u></em>

If the sides of a right triangle is 10 cm, and the other side is 8 cm, what is the hypotenuse? Round to the nearest tenth.
Advocard [28]

Answer:

Step-by-step explanation:

Pythagorean theorem,

hypotenuse² = Base² + altitude²

                     = 8²    + 10²

                   = 64 + 100

                   = 164

hypotenuse = √164 = 12.8 cm

What are the values of x in the equation 4x2 + 4x - 3 = 0?
9966 [12]

Answer:

x=  0.5

or x=  -1.5

Step-by-step explanation:

Let's solve your equation step-by-step.

4x2+4x−3=0

Step 1: Factor left side of equation.

(2x−1)(2x+3)=0

Step 2: Set factors equal to 0.

2x−1=0 or 2x+3=0

x= 1/2 or x= −3/2
