Answer:
17
Step-by-step explanation:
-(-17)=-1*-1*17=1*17=17
You need Pythagorean theorem for this.
a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.
24² + x² = 26²
x² = 676-576
x = ±√100
x = 10 (-10 is rejected because length of triangle cannot be a negative number)
Answer:
y= 8th grade class,
y + 24 =160
subtract 24 from both sides
y=136
there are 136 students in the eight grade class

Step-by-step explanation:
Answer:
X²-4x-5
5-×1=5-
5-1=4
so the Values 5 and 1
x²-x-2
2×1=2
2-1=1
the values is 2 and 1
(x-2)×(x+1)
so
x-5/(x-5)×(x+1)=2x-5/(x-2)×(x+1)
1=2x-5/x-2
x-2=2x-5
x=3
hopefully its helpful and correct
