Answer:
8
Step-by-step explanation:
If we assume the '17' is the hypotenuse ( the Q does not say)
then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles
x = 8
Answer:
B
Step-by-step explanation:
Since x is in an absolute value, we know that no matter what value we put in for x, the result will always be positive. B fits this description.
Answer:
50cm
Step-by-step explanation:
If the sides are consecutive odd integers,
Let the smallest side=y
The other sides are y+2 and y+4
The perimeter=144cm
y+y+2+y+4=144
3y+6=144
3y=144-6
3y=138
y=138/3=46cm
Therefore, the largest side of the triangle:
y+4=46+4=50cm
Therefore, the largest side of the triangle is 50cm
The answer would be A.
Explanation:
If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.
