Answer:
All you need to do is find a common denomianatorand then solve from least to greatest hope this helps!
Step-by-step explanation:
Your answer would be 17cm.
Because two sides are equal, we can label these two sides x, and the base y, and since the perimeter is 71cm, we can then write the equation 2x + y = 71.
Then we apply the changes made to our sides, so the two equal sides would become x - 4, and the base would become y + 6. We can now set these equal to each other as it states that all sides are equal when this change occurs.
Now we have a pair of simultaneous equations that we can solve with substitution firstly by rearranging the equation x - 4 = y + 6 to get x:
x - 4 = y + 6
+ 4
x = y + 10
Now we can substitute (y + 10) as x into the equation 2x + y = 71 :
2(y + 10) + y = 71
2y + 20 + y = 71
3y + 20 = 71
- 20
3y = 51
÷ 3
y = 17
I hope this helps!
Answer: 31.25 ft
Step-by-step explanation:
50 / 32 = x / 20
32x = 50(20)
x = 31.25 ft
Answer: B) quadrant IV; no
--------------------------------------------------------------
After the translation, the triangle stays in quadrant IV. It then reflects over to quadrant I, only to rotate back to quadrant IV again. The size and shape does not change. These transformations are known as "rigid transformations" which preserve segment lengths (aka keep them the same). So the final triangle is congruent to the original triangle. All that has happened is that it has moved around.
Add 2.5 to each side
C -2.5 +2.5 =< 2.5+2.5
C=< 5
=< means less or equal
