To solve this problem you must apply the proccedure shown below:
1- If the triangle is a rigth triangle, you must apply the Pythagorean Theorem. Taking the length 3 inches as the hypotenuse, which is the longest side of the triangle, you have:
a^2=b^2+c^2
c=√(a^2-b^2)
b=3/4 inches
a=3 inches
2- When you susbtitute the values, you obtain:
c=√(3 inches)^2-(3/4 inches)^2
c=2.90 inches
The answer is: 2.90 inches.
Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15

Answer:
-13 13/35
Step-by-step explanation:
5 4/7 * - 2 2/5
Change to improper fractions
5 4/7 = (7*5 +4) /7 = 39/7
2 2/5 = (5*2+2)/5 = 12/5
39/7 * -12/5 = -468/35
Change back to a mixed number
35 goes into 468 13 times with 13 left over
-13 13/35
