Answer:
c. (x + 10)(x + 5)
Step-by-step explanation:
For this case what we must observe are the following triangles:
ADB
BDC
According to the diagram, the triangles have exactly the same dimensions.
Therefore, it is fulfilled:
Then, the value of AC is given by:
Substituting values we have:
Answer:
The value of AC is given by:
option 3
Answer:
4(x - 4) = 4x - 16
Step-by-step explanation:
4(x - A) = 4x - 16
4x - 4A = 4x - 16
Equating Constant terms (terms without x): -4A = -16
A = 4
Therefore , 4(x - 4) = 4x - 16
Answer:
<h2>70%</h2>
Step-by-step explanation:
Step one:
given data
we are told that the number of people under the survey is 3000
and also that 2100 people would like to buy again, these 2100 people represent the number of people who are satisfied with the type of car.
Step two:
Therefore the percentage of this number related to the total people under the survey is given below
=2100/3000*100
=21//30*100
=7/10*100
=7*10
=70%
<u>Hence 70% of the people surveyed are satisfied with the type of car</u>
