Answer:
6x +10
Step-by-step explanation:
Perimeter = 2*(length + width)
= 2* (x+6 + 2x-1)
=2*(3x +5)
=2*3x + 2*5
=6x + 10
Answer:
An isosceles triangle is one with 2 sides of the same length.
As far as I can find, there are 6 different mom congruent triangles.
Answer:
6+f=21
Step-by-step explanation:
Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
