Everything looks good, but I would write LJ = LJ (or JL = JL) for line e just so it's clear you're talking about the same line segment.
Though to be fair, JL is the same as LJ so it really doesn't matter. I guess it will depend on how picky your teacher is.
Also, I almost forgot, but line c should have angle markers so that your teacher knows you are talking about two angles.
Hmmmm I really do not know but let me calculate it. U divide i think. O sorry
Answer:
xsqrt(2)
Step-by-step explanation:
sqrt(14x^3) / sqrt(7x)
We know sqrt(a) / sqrt(b) = sqrt(a/b)
sqrt(14x^3/7x)
sqrt(2x^2)
sqrt(ab) = sqrt(a) sqrt(b)
sqrt(2) sqrt(x^2)
sqrt(2) x
xsqrt(2)
If 5/8 students are boys, then 3/8 students are girls. You want to multiply 3/8 by 32. You can simplify 8 and 32. You cross out 8 to get 3/1 * 4 or 12 which means 12 students in the class are girls.
The two cities are 7 inches apart, so they are 7*20=140 miles apart.
Divide 140 miles/35 miles, and you'll get 4. The scale is 3 inches, so your answer is 12 or C.
