Answer:
n = 288
Step-by-step explanation:
18 sqrt(8) - 8 sqrt(18) = sqrt(n)
18 sqrt(4*2) - 8 sqrt(9*2) = sqrt(n)
We know that sqrt(ab) = sqrt(a) sqrt(b)
18 sqrt(4) sqrt(2) - 8 sqrt(9) sqrt(2) = sqrt(n)
18*2 sqrt(2) - 8*3 sqrt(2) = sqrt(n)
36 sqrt(2) - 24 sqrt(2) = sqrt(n)
12 sqrt(2) = sqrt(n)
Square each side
(12 sqrt(2))^2 = (sqrt(n))^2
12^2*(sqrt(2))^2 = n
144 *2 =n
288 =n
Answer:
75000
Step-by-step explanation:
We can use ratios to solve. Put the scale length over the real length
1 15
------------ = ----------------
5000 x
Using cross products
1x = 15*5000
x =75000
Answer:
7. Corresponding Angles Theorem
8. Alternate Interior Angles Theorem
9. Alternate Exterior Angles Theorem
10. Supplementary Angles Theorem
Step-by-step explanation:
Answer: 1 1/12
Step-by-step explanation:
1/3 + 3/4 =
1/3 x 4= 4/12
3/4 x 3 = 9/12
9/12 + 4/12 = 13/12 = 1 1/12
