Answer:
58 units squared
Step-by-step explanation:
**I'm doing the question with the 7 by 3 triangle in the picture, not 777 by 333**
Pythagorean Theorem: , where c is the length of the hypotenuse.
The given sides are legs, therefore,
c is also one of the sides of the square. A square's area is one of the sides' lengths squared, so:
Answer: 27<AB<81
Step-by-step explanation:
We can generalize the triangle inequality theorem to say that the sum of the lengths of the two shorter sides must be greater than the length of the longest side.
Case 1: AB is the longest side
Case 2: BC is the longest side
So,
Poor kid, next time ask your parents or teacher for help or try to find a smart friend that can help you. Go to bed if it is late and make sure you understand your homework before taking it home. Good luck!! :))
Let the numbers be x and y
According to the data : xy=-15 and x+y=-7
xy=-15
x+y=-7
y=-7-x
x(-x-7)=-15
y=-7-x
-x^2-7x=-15
y=-7-x
x^2+7x-15=0
y=-7-x
x=(-7±sqrt(7*7+4*15))/2
y=-7-x
x=(-7±sqrt(109<span>))/2
</span>
Goes to two systems.
1)
y=-7-x
x=(-7+sqrt(109<span>))/2
</span>
y=-7+3.5-sqrt(109<span>))/2
</span>x=(-7+sqrt(109<span>))/2
</span>
y=-3.5-sqrt(109<span>))/2
</span>x=(-7+sqrt(109<span>))/2
</span>
2)
y=-7-x
x=(-7-sqrt(109<span>))/2
</span>
y=-7+3.5+sqrt(109))/2
x=(-7-sqrt(109))/2
y=-3.5+sqrt(109))/2
x=(-7-sqrt(109<span>))/2</span>
