LMNO is a parallelogram.If NM = x+15 and OL = 4x +6, find the value of x and then find NM and OL.

3. studyopen101 Group Title

Well, since it is a parallelogram, you set NM = OL. Then you would get x=3. Each side would be 18.

4. tayler_miller Group Title

it looks like this|dw:1325244073059:dw|

5. tayler_miller Group Title

so whats the valuce of x?

6. snowballhockey Group Title

idk i am in 6ht grade so sorry

7. tayler_miller Group Title

oh its okay (:

NM = x+15 and OL = 4x +6 And we know that NM = OL because a parallelogram is a quadrilateral that has two pairs of parallel sides. Solve for x x+15=4x+6

9. tayler_miller Group Title

so what does x equal ?

10. cazil Group Title

You have to solve the equation x+15=4x+6 Isolate the variable x on one side (what ever you do to one side of an equation you have to do to the other) subtract x from both sides x-x+15=4x-x+6 15=3x+6 subtract 6 from both sides 15-6=3x+6-6 11=3x divide both sides by 3 $\frac{11}{3} = \frac{3x}{3}$ and you are left with 11/3 = x

11. tayler_miller Group Title

but im left with afraction so do i have to divide 11 by 3 ?

12. cazil Group Title

You can use the fraction in NM = x+15 and OL = 4x +6 $NM=\frac{11}{3} + 15$

13. cazil Group Title

Do you know how to add fractions with unlike denominators?

14. snowballhockey Group Title

no

15. cazil Group Title

$\frac{11}{3}+\frac{15}{1}$

16. snowballhockey Group Title

Do ththis
