Answer:
$96.95
Step-by-step explanation:
13.85*7=96.95
It is -6/10 and 6/10, just take the square roots of the top and bottom and make it a fraction, square root of 36 is 6 and 100 is 10 so you get 6/10 and since 2 negative make a positive, you can have the negative sign next to the whole fraction, not the number though.
Answer:
60 degrees
Step-by-step explanation:
All angles of a triangle will add up to equal 180 degrees.
Set up an equation to solve for x:
9x - 3 + 50 + 9x + 7 = 180
Combine like terms
18x + 47 + 7 = 180
18x + 54 = 180
Subtract 54 from both sides
18x = 126
Divide both sides by 18
x = 7
Now plug in 7 for x in the expression for angle A:
9(7) - 3
63 - 3
60
Check work:
60 + 50 + 9(7) + 7 = 180
110 + 63 + 7 = 180
173 + 7 = 180
180 = 180
Correct
Answer:
22
Step-by-step explanation:
first find the square root of all the sides then add them up and divide by two and your answer should be 22 hope this helps
