One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:
and x = 17, so simplify and
so
The discriminant is <span>−<span>8
</span></span>f<span>(x)</span>=−3<span>x2</span>−2x−1
is of the form <span><span>a<span>x2</span>+bx+c</span>
</span>,with <span><span>a=−3</span>
</span>, <span><span>b=−2</span>
</span> and <span>c=−<span>1</span></span>
Each friend had 2/5 of a bag of peanuts leftovers and they should've bought 2 fewer bags
Which means that there are 2 extra bags
So 2/5 multiplied by the number of friends gives you 2 extra bags
Let x be the number of friends
x(2/5) = 2
2x = 10
x = 5
So 5 friends went to the game.
Answer:
x² - 7 = 0
x² = 7
x =
or x=
x² + 2 = 0
x² = - 2, this part of equation has no solutions.
