X2+8x+y2−4y+4=0 is the Answer
Answer:(5,3)
Step-by-step explanation: 3+1=4 4+1=5 then second number 1+1=2 2+1=3
For side length s, the area of a square is given by
... A = s²
Then the side length can be found to be
... s = √A = √(506.25 ft²) = 22.5 ft
The perimeter is the sum of the lengths of the four equal sides.
... P = 4s = 4·(22.5 ft) = 90 ft
Stevan will need 90 ft of fence to complete the job.
Answer:
15/12 - 4/12
Step-by-step explanation:
1 1/4 = 5/4
5/4•3 = 15/12
1/3 = 4/12
Answer:
b) 5.8
Step-by-step explanation:
<u>Explanation</u>
Given diagram the angles are (9 x + 6)°, (10 x + 7)°, (10 x - 1)°
we know that the sum of the angles of the triangle is equal to 180°
∠A +∠B +∠C = 180°
(9 x + 6)°+(10 x + 7)°+ (10 x - 1)° = 180°
On simplification , we get
29 x + 12 = 180
29 x = 180 -12
29 x = 168
x = 5.79 ≅ 5.8
