Answer:

Step-by-step explanation:






Answer:
20.5
Step-by-step explanation:
Let's label the vertices ABC as in the diagram below. Then
Data:
α = 34 °
β = 90 °
c = 17
Calculation:
cosα = AB/AC
Multiply each side by AC
ACcosα = AB
Divide each side by cosα
AC = AB/cosα = 17/cos34 ≈ 17/0.8290 ≈ 20.5
First, do 5 = 12 = 17.
Look at the numbers you have.
What numbers can make 17?
You basically add ().
You add the () between 2 x 6 (2x6) to show that you do that first.
Then, once you get the answer for that, add 5.
5+(2x6) = 17.
I hope this helps! :D
-10v – 3(8 + v)
mutiply the bracket by -3
(-3)(8)= -24
(-3)(v)= -3v
-10v-24-3v
-10v-3v-24 ( combine like terms)
answer:
-13v-24 or -24-13v
