Answer:
Presuming she eats the same amount of sweets each day, 9 days
Step-by-step explanation
Answer:
392
Step-by-step explanation:
3 rectangular faces
7 x 16 = 112
7 x 16 = 112
7 x 16 = 112
2 triangular faces
1/2 x 7 x 8 = 28
1/2 x 7 x 8 = 28
Total surface area:
112 + 112 + 112 + 28 + 28 = 392
Answer:
First choice is the correct one
Explanation:
The given is:
[(x+5) / (x+2)] - [(x+1) / x(x+2)]
First, we will need to have a common denominator and then we will solve the subtraction normally. To get a common denominator, we will have to multiply both numerator and denominator of first term by x.
Therefore:
[(x+5) / (x+2)] - [(x+1) / x(x+2)] = [x(x+5) / x(x+2)] - [(x+1) / x(x+2)]
= [x(x+5)-(x+1)] / [x(x+2)]
= (x^2 + 5x - x - 1) / [x(x+2)]
= [(x^2 + 4x - 1)] / [x(x+2)]
Hope this helps :)
All triangles angles in the inside add up to 180, so 180-76-72=32
