You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be \frac{BD}{AD}=\frac{CD}{BD} where BD is your altitude. The formula then, filled in accordingly, would be \frac{10}{x}=\frac{4x}{10}. We cross multiply to get that 4x^2=100. Divide both sides by 4 to get x^2=25, so x = 5. Choice C is the one you want.

For #10

x=2     w(x)= 5

x=0     w(x)=-9

x=1     w(x)=-1

x=4    w(x)=7

To get these answers, you must use the p(x) table. When x=2, p(x)=6. So you would substitute p(x) for 6 and solve. That would be what you would do for the rest of teh problems.

For #12, the answer would be 5x^2+15x+5

Just mutiply the areas of the out side and inside and subtract them

Please help me solve my problem!!!
Nookie1986 [14]

Answer:

B. sometimes

Step-by-step explanation:

Consecutive angles of a parallelogram are same side interior angles of two parallel lines cut by a transversal, so they are always supplementary.

Supplementary angles are two angles whose measures add to 180 deg.

If two angles are supplementary and one angle measures 90, then the other angle also measures 90 deg, and the two angles are congruent. If one angle measures less than 90 deg, then the other measure more than 90 deg and are not congruent. Therefore, these angles may or may not be congruent.
