Answer:

16m   - 135

Step-by-step explanation:

-5(m + 9) + 3m + 6(3m – 15)

Distribute

-5m + -5*9 +3m +6*3m -6*15

-5m -45 +3m +18m -90

Combine like terms

-5m +3m +18m    -45-90

16m   - 135

Answer:

16m - 135

Step-by-step explanation:

Distribute the -5 on -5(m+9) to make -5m-45

Do the same with 6(3m-15) to get 18m - 90

Then arrange the like terms together

-5m + 3m + 18m - 45 - 90

Add the ones with variables

-5m + 3m + 18m = 16m

Then the regular ones

(-45) + (-90) = -135

And finally,

16m -135

△ABC △ABC  is similar to △LMN △LMN . Also,  side AB measures 5 cm,  side AC measures 7 cm, and  side L​M measures 35 cm.
dolphi86 [110]
You need to apply "Proportionality theorem" here:
LM / AB = LN / AC
35 / 5 = LN / 7
LN = 7 * 7
LN = 49

In short, Your Answer would be 49 cm

Hope this helps!

Find the sum: 4 radical 3 + 11 radical 12
Ksenya-84 [330]

Answer:

26\sqrt{3}

Step-by-step explanation:

We want to find 4\sqrt{3} +11\sqrt{12}. 11\sqrt{12} can be written as 11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}, so we can now write our original equation as: 4\sqrt{3}+22\sqrt{3}.

We can combine like terms: 4\sqrt{3}+22\sqrt{3}=26\sqrt{3}

Hope this helps!
