Answer:
150
Step-by-step explanation:
because acute angle is less than 90 degree
Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :
The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
Well, to find u, we have to remove all that is attached to it so the equation can just be u=...
To find u, you have to remove what is attached to it, and that is -12. Then you have to look at the relationship between the -12 and u. The relationship is multiplication, and the opposite of multiplication is division, so all you have to do is divide both sides by -12. So;
-12u/-12=-24/-12
The -12 cancels the -12, leaving u and the - in 12 cancels the - in 24. Leaving 24/12. And that is 2. Written as;
u=2
Hope i helped. If you have any more problems, let me know.
Answer:
n=25
Step-by-step explanation:
-3n-8=-83
-3n-8+8=-83+8
-3n=-75
n=25
Step-by-step explanation:
Mx+B=y
B=y-Mx
Ax+By=C
Ax=C-By
Ax/A=C-By/A
x=C-By/A
Bh/2=A
2 x Bh/2=A x 2
Bh=2A
Bh/B=2A/B
h=2A/B
