Answer:
59) not similar
60)
Step-by-step explanation:
59) The ratios of the side lengths shown cannot be reduced. They are different, so the triangles are not similar.
7:8:12 ≠ 6:7:11
__
60) The side length ratios both reduce to 8:7:10, so the triangles are similar.
∆ABC ~ ∆JKL
The scale factor is LJ/CA = 25/20 = 5/4. (Multiplying ABC by 5/4 will give JKL.)
<span>2x^2+8x-7=-2
</span><span>2x^2+8x - 5 = 0
using the formula:- x = [-8 +/- sqrt(8^2 - 4*2*-5) ] / 4
= -2 +/- sqrt 104)/2
= 0.5495 , -4.549

Answer:
25/28
Step-by-step explanation:
5/4 x 5/7 = 25/28
Answer:
I believe it's B (location C on the number line).
Step-by-step explanation:
You would add -1/2 to 1 1/2 but because the 1/2 is negative, it would subtract from the other 1/2 in 1 1/2 therefore leaving you with the answer 1, which location is where C is plotted.
