Answer:
8 hours
Step-by-step explanation:
First you divide 126 by 3 to get the Miles Per Hour, you should get 42 Miles Per Hour, then, just divide 336 by 42 to get the numbers of hours he will have to drive, (which is 8)
Let's start studying case by case:
Ann:
3x ^ 2 -24x-27
3 (x ^ 2 -8x-9)
3 (x + 1) (x-9)
Note:
(1) * (- 9) = - 9
(1) + (- 9) = - 8
check:
3 (x ^ 2-9x + x-9)
3 (x ^ 2-8x-9)
3x ^ 2-24x-27
She did it correctly.
Max
3x ^ 2 -24x-27
(3x + 3) (x-9)
note:
(3) * (- 9) = - 27
(3) + (- 9) = - 6 (incorrect: the result must be -24)
=47.55
Divide 63.4 by 100 and multiply by 75 (works with any percentage)
Answer:
SAS
Step-by-step explanation: every triangle contains a total of 180 degrees if you substract 180 by 60+70(which is 130) you would get 50 degrees which is the exact degree missing in the first triangle, so after confirming that both triangles have an equal degrees on each side the answer would be SAS (which stands for Side-Angle-Side), SAS is the answer you would give to triangles that are congruent(equal)
