Answer:
x=0, x=-7
Step-by-step explanation:
x(x+7)=0
Solution 1:
x=0
Solution 2:
x+7=0
x=-7
Answer:
Step-by-step explanation:
Alright, lets get started.
Area is given as 49 square inches.
The formula for area A = ![\frac{1}{2}*base*height](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2Abase%2Aheight)
base is given as x
Height is given as x
Hence area is A
A = ![\frac{1}{2}*x*x = 49](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2Ax%2Ax%20%3D%2049)
Multiplying 2 in both sides
![x^2=98](https://tex.z-dn.net/?f=x%5E2%3D98)
Taking square root on both sides
![x=9.9](https://tex.z-dn.net/?f=x%3D9.9)
hence the answer is x = 9.9 in : Answer

Step-by-step explanation:
second convert 154into mettres
Answer:
∠ ABC = 22°
Step-by-step explanation:
OA = OB ( radii of circle )
Then Δ OAB is isosceles with base angles congruent , that is
∠ OBA = ∠ OAB = 17x
The sum of the 3 angles in the triangle sum to 180°
17x + 17x + 11x = 180
45x = 180 ( divide both sides by 45 )
x = 4
Then
∠ OBA = 17x = 17(4) = 68°
BC is a tangent so ∠ OBC = 90°
∠ ABC = 90° - ∠ OBA = 90° - 68° = 22°
I would say 2.....sorry if I am wrong
