Just divide: 1240 divided by 20 which is 62.
They sold 62 pictures.
Hope that helped:)
Answer:
if i draw a line from s ro hg then its value should be 12 cm. and should form a right angle triangle. it is not fulfilling pytgogerous property..
64 and 24 can be combined so if you were going to simplify this your answer would be 88 - 82g.
You would add 64 + 24 = 88 and since you can't subtract 88 and 82 because they both don't have a variable your answer would be 88 - 82g.
Hope this Helps!!
Answer:
g(x) = x²
The graph of g(x) is the same with the graph of f(x)
Step-by-step explanation:
* Lets explain how to solve the problem
- If the function f(x) reflected across the x-axis, then the new
function g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then the new
function g(x) = f(-x)
* Lets solve the problem
∵ The parent function f(x) = x² is represent by upward parabola
with vertex (0 , 0) (red graph in the attached picture)
∵ f(x) is reflected across the y-axis
- As the rule above reflection across the y-axis change the sign of x
∴ g(x) = f(-x)
∵ f(x) = x²
∴ g(x) = (-x)²
- Remember (-ve)^even number = (+ve)
∴ (-x)² = x²
∴ g(x) = x²
- The function g(x) is represent by upward parabola with vertex
(0 , 0) (black graph in the attached picture)
∴ The graph of g(x) is the same with the graph of f(x)
- The red graph and the black graph are coincide

Answer:
not similar
Step-by-step explanation:
For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...
180° -81° = 99°
If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.
ABC angles: 60°, 81°, 39°
FED angles: 59°, 81°, 40°
