Answer:
1) x(x+7)
3) (x+5)*(x+4)
4) (x-6)*(x-8)
5) x(2x+21)+11
6) 5(a-5)*(a+5)
7) (4x+3)*(2x-3)
8) 4( x²-6xy+8)
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
If R(-2), then x = -2. Just plug in -2 for x. -2^2 - 3(-2) - 1 = 4 + 6 - 1 = 10 - 1 = 9. The answer is 9.
Answer:
Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.
