7*40 = 280, 7*2 = 14,
add both and get 280+14 = 294
if you are trying to make a simplified fraction 3/6
1.) 32.89
2.) 480
3.) 14
4.) 25.2
Hope this helps! Can I please have brainliest?
The answer is x² + 23x + 49
The area (A) of the shaded region is the difference between the area of the rectangle (A1) and the white square (A2).
A = A1 - A2
A1 = (x + 10)(2x + 5)
= 2x² + 5x + 20x + 50
= 2x² + 25x + 50
A2 = (x +1 )² = x² + 2x + 1
A = A1 - A2
= 2x² + 25x + 50 - (x² + 2x + 1)
= 2x² + 25x + 50 - x² - 2x - 1
= x² + 23x + 49
