The question is asking to choose among the expression that represents the perimeter of the picture frame where as a rectangular picture frame has a width of 9cm and length of x cm and base on the fact, I would say that the answer would be 2x times 18. I hope you are satisfied with my answer
4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
Answer:
Force F = 60 ×10⁻⁵ N
Step-by-step explanation:
Given that mass of the given object (m) = 30 grams
Given that the acceleration
a = 2 m/s²
<u><em>Force:-</em></u>
The push or pull on an object with mass that causes it to change its velocity
- Force can make a body that is rest to move
- it can accelerate the speed of a moving body
<u><em>Formula for force</em></u>
The formula for force F = m a
F = 30 × 2
F = 60 gm/s²
F = 60 ×10⁻⁵ N (∵ 1 d y n = 1gm² = 10⁻⁵N
Answer:
it depend on the question but if it is asking if they have the same answer then it is true
Step-by-step explanation:
For this case, we observe that the triangles are similar.
We observe that the triagnules have three equal angles.
Therefore, to find the value of x we can use the following relationship:

Clearing x we have:
Answer:
The value of x is given by:
x = 6.25
