Primitevly do it like:
6v-13v-18=-81
- 7v= -63
v=9
P.S Strongly recommend to learn algebra's basics
Answer:
Obtuse triangle.
Step-by-step explanation:
Obtuse = angle that is bigger than 90°
Answer: 3668.94 m^2
Step-by-step explanation:
35.7 * 15.1 = 539.07
35.7 * 15.1 = 539.07
25.5 * 15.1 = 385.05
25.5 * 15.1 = 385.05
35.7 * 25.5 = 910.35
35.7 * 25.5 = 910.35
539.07 + 539.07 + 385.05 + 385.05 + 910.35 + 910.35 = 3668.94
Okay so.
2/5=24/60 (multiply 2/5 by 12)
2/3=40/60 (multiply 2/3 by 20)
1/4=15/60 (multiply 1/4 by 15)
Then,
Add 24/60 with 40/60 which is 64/60 after you get that you subtract by 15/60 and you get 49/60.
Hope this helps!^^
Step-by-step explanation:
Let's call L the length and W the width. The length is 10 feet longer than the width, so:
L = W + 10
The area is the length times width, so:
119 = LW
Substituting:
119 = (W + 10) W
119 = W² + 10W
0 = W² + 10W − 119
0 = (W + 17) (W − 7)
W = -17 or 7
Since W must be positive, W = 7.
L = W + 10
L = 17
The length and width are 17 feet and 7 feet, respectively.
