Ok so if it has roots of -3 and 5 it should be divisible by (x+3) and (x-5) and it is also divisible by 2
Therefore it is divisible by 2(x+3)(x-5)
If you multiply that out you get 2x^2 -2x -15
Since it's a square it must have 4 sides.
20÷4=5
area=l×w or b×h
5×5=25 (the sides of a square have the same length)
the area of the photograph is 25in²
hope this helped

Answer:
45
Step-by-step explanation:
To know how many 1/5 s are in 9, we will take the ratio of both numbers as shown;
9:1/5
= 9 ÷ 1/5
= 9 * 5/1
= 9 * 5
= 45
Hence there are 45 1/5s in 9
Answer:
162°
Step-by-step explanation:
To convert from radian to degree measure
degree measure = radian measure × 
, then
degree = 
× ( cancel π and 10/ 180 to simplify )
= 9 × 18
= 162°
