Answer:2 pizzas
Step-by-step explanation:
2 2/3 and 2 5/6 can both be rounded to 3. Double that and you get 6. Since there were 8 pizzas originally,subtract 6 from 8 to get 2 remaining pizzas.
Answer:
See proof below
Step-by-step explanation
cot^2(x) - csc^2(x) = -1
In trigonometry identity
cot^2x = cos²x/sin²x
Csc²x = 1/sin²x
Substitute into the original expression
cos²x/sin²x - 1/sin²x
Find the LCM
(Cos²x-1)/sin²x .... *
Recall that sin²x+cos²x = 1
Sin²x = 1-cos²x
-sin²x = -1+cos²x
-sin²x = cos²x-1 .... **
Substitute ** into *
(Cos²x-1)/sin²x
-sin²x/sin²x
= -1 (RHS)
Therefore cot^2(x) - csc^2(x) = -1 (Proved!)
<span>13 more than 4 times a number is negative 91
</span>Convert to numbers:
13 more than 4: 4+13
times a number: (x)
is negative 91: = -91
Put it together:
4x+13=-91
x = -26
The possible side lengths of a triangle are 6cm , 9cm, 17cm
Answer:
AB = 6.5
Step-by-step explanation:
If you use the distance formula, you can find the answer.

Therefore, the distance between the points A(0, 1) and B(6, 3.5) is 6.5. Hope this helps!
