1. Perfect square trinomials, are 2nd degree polynomials, of the form
so that
, which can be written as perfect squares.
2. For example
3. Thus
are perfect square trinomials.
4.
5. In the first case -b=20, so b=-20. In the second case, -b=-20, so b=20.
6. b∈{-20, 20}
Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
5:3
5+3=8
8 units
800=8 units
divide oth sides by 8
100=1 units
soccer=5 units=5 times 100=500
social=3 units=3 times 100=300
500 soccer players
Answer:
2/-3 is the answers for the question
Step-by-step explanation:
please give me brainlest to me please
In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.
..........(Equation 1)
Checking the diagram given, we see that:
VT=y, WS=22, VU=8, ST=x-2
WU=WV+VU=12+8=20
TU=5
SU=ST+TU=(x-2)+5=x+3
Thus, substituting the required values in (Equation 1) we get:
Now, as can be clearly seen, to find y we will use the first two ratios as:
In a similar manner, to find the value of x we can use the last two ratios:
After cross multiplication we get:
Which can be simplified as:
Thus, 
Therefore, the required answer is:
x=9.5 and y=8.8
