Answer: C
Step-by-step the table that's flipped the y and x values of the given table
The solution of the equation x2+7x is 0, -7 using the quadratic formula.
Step-by-step explanation:
x2 + 7x = 0
-b ± √
b2 - 4(ac)/ 2a
substitution,
a = 1, b = 7, c = 0
= -7 ± √(7)2 - 4(1 x 0) / 2 x 1
= - 7
± 7 / 2
x = 0 , -7
4.24 is the answer I believe,
Well, the sum of all internal angles in a triangle, isosceles or whatever else, is always 180°, so the sum of all those three folks, will be 180 then
so.. hmmm let's say the smallest angle is "a" units
twice that is, 2*a, or 2a
25 larger than that? is well 2a + 25
so... the other two twin angles, are 2a+25 each
thus a + (2a + 25) + (2a + 25) = 180
solve for "a" to find the smalles one
what about the twins? well, each is 2a + 25
