Answer:
b=44
b=44 - 9
b=44 + 5
x+x+x = 44
x + (x-9) + (x+5) = 44
3x - 4 = 44
+4
3x =48
÷3
x=16
So, first photo contains 16 birds.
x=16
(x-9) - - > 16-9 = 7
(x+5) - - >16+5=21
16 + 7 + 21 =44
Answer is 16 birds in first photo
Hope this helps!
Answer:
<h2>
x² + 9 + 6x </h2>
Step-by-step explanation:
expand and simplify (x+3)²
(x+3)² =
x² + 9 + 2 × x × 3 =
x² + 9 + 6x
Step-by-step explanation:
-0.45 = 9/20
2.77= 2 7/9
5.55 = 5 5/9
( -2, 1 ) is the image of ( -1,2 ) reflected across the line y=-x.
