x^2 – 8
-----------
x + 6
Let x = -2
(-2)^2 – 8
-----------
-2 + 6
Exponents first
4 – 8
-----------
-2 + 6
Then complete the numerator and denominator
-4
-----
4
Then divide
-1
1. find the LCD of 3 and 4 (12). so now your fractions are 5 4/12 and 3 9/12 perimeter is 2l + 2w so 2 (5 4/12) + 2( 3 9/12) = 10 4/12 + 7 6/12 = 17 10/12 or 17 5/6. this is reasonable because that the average perimeter of a sandbox.
2. LCD again is 12, so the fractions are 5 10/12 and 2 1/12. turn those into mixed fractions and get 70/12 and 25/12. 45/12 or 3 3/4. So she babysits 3 3/4 hours during the week.
3. The LCD for this is 8. now the fractions are 2/8 and 1 7/8 or 15/8. add 15/8 and 2/8 to get 17/8 or 2 1/8. He is using a total of 2 1/8 cups of flour.
4. 0.2
5. 0.054
6. 0.024
Answer:
0.621
Step-by-step explanation:
Number of people that have run a red light in the last year = 290
Number of people that have not run a red light in the last year = 177
Total number of respondents = 290 + 177
= 467
Pr(if a person is chosen at random, they have run a red light in the last year) = 
= 
= 0.621
The probability that if a person is chosen at random, they have run a red light in the last year is 0.621.
Answer:
44 degrees
Step-by-step explanation:
there's two ways u could do this. One is all triangles add up to 180 degrees. u simply ignore the outside angle of 136 degrees, and add 62 and 74, and u get 136. take 180-136, and u get 44.
Another way is all strait angles add up to 180 degrees. take 180-136, and u get 44 degrees
Hope this helps and have a nice day :) :) :)
