Answer:
AP=a+(n-1)d is the formula
Answer:
11.0 cm
P=38 cm
38/3=12.67cm length of one side
Base of triangle = 12.67/2 =6.34 cm
Use formula 
x = altitude of triangle
Answer:
=2x+723
Step-by-step explanation:
y+2x−3+272−y−3
=y+2x+−3+729+−y+−3
Combine Like Terms:
=y+2x+−3+729+−y+−3
=(2x)+(y+−y)+(−3+729+−3)
=2x+723
Ellipses, parabolas, and infinity. A parabola can be defined as the locus of points equidistant from a fixed point (called the focus) and a fixed line (called the directrix). But we know from projective geometry that parabolas and ellipses are essentially the same object.
Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
