The sides of a triangle must satisfy the triangle inequality, which states the sum of the lengths of any two sides is strictly greater than the length of the remaining side.
We really only have to check if the sum of the two smaller sides exceeds the largest side.
A. 5+6>7, ok
B. 6+6>10, ok
C. 7+7=14 Not ok, this is a degenerate triangle not a real triangle
D. 4+6>8 ok
Answer: C
Answer:
1462.5
Step-by-step explanation
225 mph means of course 225 miles per hour
225 x 6 is 1350 and then you have to do 225/2 which is 112.5 to find what half of 225 is then you add 1350+112.5 to get 1462.5
2 digit meaning that it has 2 numbers. For example, 66 is a two digit number.
Now, they also said it must be prime, meaning that its factors can only be 1 and itself.
Also, it must be odd.
Answer: 67
Now, do the same, except the number must be composite, as meaning that it has other factors.
Answer: 21
Answer:
A.81/4
Step-by-step explanation:
x^2-9x
This is in the form x^2 + bx
To complete the square, we take b/2 then square it and add it
b =-9
b/2 = -9/2
(b/2) ^2 = (-9/2) ^2 = 81/4
The answer is {-2, 2}, first you get p by itself by dividing 4 by 2. Then you have <span>|p| = 2, so p can be -2 or 2.</span>
