Answer:
Similar, SSS similarity, ΔLRS
Step-by-step explanation:
First, compare the ratios of the shortest sides:
LN / LS = 112 / 24 = 4⅔
And the longest sides:
LM / LR = 168 / 36 = 4⅔
And the middle:
MN / RS = 154 / 33 = 4⅔
The triangles' sides are proportional. Therefore, by SSS similarity, the triangles are similar.
No that statement is not always true. There is only one solution to this equation.
Answer:
none of the above
Step-by-step explanation:
the answer is -3/4
Add 21 to both sides: 70n=98
Divide each side by 70: n=98/70
Reduce the fraction: n=7/5
They are called identities because:
w-x = 0
w = x (carry x to the other side) is the same as x = w
in the other case:
wx-x = w / divide by w on both side
x -x = 0
x = x (carry x to the other side)
In both cases the equations are the same.
