R = 7 d = 14 (to find the radius d ÷ 2) h = 10
(2πr²)
2 x 3.14 x (7x7)
2 x 3.14 x 49 = 307.72
(πdh)
3.14 x 14 x 10 = 439.6
Take the two answers and add.
307.72 + 439.6
Final answer = 747.32
So:
(x-4)(x+2) / (x-4)(x+4)
We cancel out the x - 4:
(x+2)/(x+4)
Restrictions: x ≠ 4, x ≠ -4
Answer: -4c+12
all real numbers
Step-by-step explanation:
Answer:Her score is 26
Step-by-step explanation:
To find the answer, we must deduct the total amount of points that are answered correctly
By the total amount of points that are answered incorrectly.
Because = 1 answered correctly = 4 points
= 1 answered incorrectly = deduct 7
points
So= 87 answered correctly × 4 points
= 348 points
So= 46 answered incorrectly × 7 points
=deduct 322 points
Then the answer will be= 348 - 322= 26
Hope this helps!
