Answer:
2 (real) solutions.
Step-by-step explanation:
A quadratic always has two solutions, whether they are real or complex.
Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).
In the case of
x^2+3x = 3, or
x² + 3x -3 = 0
we apply the quadratic formula to get
x = (-3 +/- sqrt(3^2+4(1)(3))/2
to give the two solutions
{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}
both of which are real.
Answer:
A) Both estimates are slightly larger, so it is reasonable.
Step-by-step explanation:
Since 1/2 = 5/10
And 1/5 = 8/40
<u>Both estimates are larger</u>
So since the equation is right by 100 it equals 100 sooo
6x + 52 = 100
now we solve
6x = 48
x = 8
and then for zz it’s 360 - 200
which is 160
divide by 2 so
80
SOOOO
x = 8
z = 80
sorry the explaining sucks ;-;
Always check the prime factorization for the terms under the radical sign so that you know which perfect squares can be removed...
√26
√(2*13) Since both term are primes to the first power, there is nothing to move out from under the radical and it is already in its simplest form.
