No. Each side must be less than the sum of the remaining two sides.
10 ≮ 5+1
Answer:
$100
Step-by-step explanation:
40x30=1200
1200/12=100
Since 6 is positive, it's (x+blank)^2
6/2=3, and (x+3)^2 = x^2+6x+9. We have x^2+6x-2, so we have to add 9 to both sides to get (x+3)^2-2=9, then subtract 9 from both sides to get
(x+3)^2-11=0, or (x+3)^2=11. Square root both sides to get x+3=sqrt(11), and x=sqrt(11)-3, which is approximately 0.32
Answer:
No, (8,5) is not a solution of y > x + 7
Step-by-step explanation:
Hope you got it.
Let
cos x=7/18
x=arc cos (7/18)-----> using a calculator-------> x=67.11°-----> x=1.17 radians
the answer is
x=67.11° or x=1.17 radians
