Answer:
Option 3) 24 is right.
Step-by-step explanation:
Given in the picture is a triangle LMN. sides are MN = 12, LN = 21 and LM = x cm
Also MO is the angle bisector of angle M.
By applying angle bisector theorem for triangles we get
LM/MN = LO/NO
i.e. x/12 = 14/7
Simplify to get x = 24
Hence option 3 is right
Verify:
Check whether angle bisector theorem is true.
The proportion LM/MN =24/12 = 2
The proportion LO/NO =14/7 =2
Both are equal and hence verified
No, She is not correct.
Step-by-step explanation:
To find the greatest common factor of the expression 20x + 100xy.
Given expression 20x + 100xy.
Let us factor the expression 20x + 100xy.
Now take the common factor in the expression 20x + 100xy.
The common factor is 20x.
So, 20x + 100xy = 20x( 1+ 5y)
But Claudia says that the greatest common factor is 20(x+5xy).
The GCF is wrong.
So, she is not correct.
Adults and children of all ages! In order to find the most accurate results, you need a larger sample space :)
Answer:
C. Marie should make sure she surveys both the fathers and mothers.
Yes, that's quite true. It's also a real number, and a negative number.
