9 3/10- 1 7/10
8 13/10 - 1 7/10
7 6/10
7 3/5
Answer:
37
Step-by-step explanation:
the formula for this is:
A^2 + B^2 = C^2
if you substitute them:
12^2 + 35^2 =C^2 -> 144+ 1225= 1369
and the square root of 1369 is 37
hope this helps!!!
Answer:
The first option x = y
Step-by-step explanation:
If 7x = 7y, then...
7x = 7y
7x / 7 = 7y / 7
x = y
Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
