Answer: 2 1/4
Step-by-step explanation: theirs 2 whole so with that theirs another circle cut in 4th's and 1 is shaded so 1/4.
16x² - 49
= (4x)² - 7²
Identity =》 a² - b² = (a + b) (a - b)
(4x)² - 7²
= (4x + 7) (4x - 7) [3rd option]

Answer:
BC = 5
Step-by-step explanation:
Of course, this geometry program can tell you the length of BC.
__
If you follow directions, you get a right triangle BCF that has leg lengths 3 and 4. The Pythagorean theorem then tells you the length of hypotenuse BC is ...
BF = 4 -1 = 3
FC = 4 -0 = 4
BC² = BF² +FC²
BC² = 3² +4² = 9 +16 = 25
BC = √25
BC = 5

Answer:
1/9
Step-by-step explanation:
Pairs that sum to 5 are (1,4), (2,3), (3,2), (4,1). There are 4 ways you can get that sum out of 36 possible outcomes. Assuming each outcome is equally likely, the probability of a sum of 5 is ...
p(5) = 4/36 = 1/9
