Answer:
32
Step-by-step explanation:
Since AP and BP are tangents from the same point, they are equal. So 2x+12=4x-8. So solving for x, we get 2x=20. So x=10. Plugging that in, we get 20+12=32. So the answer is 32.
Answer:
y = 2
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
y = (
)² = 2
Answer:
~31.42
Step-by-step explanation:
I multiplied 10 x pi and it gave me 31.4159265359 and I rounded up to 31.42
Answer:
The answer is 
or 
Step-by-step explanation:
we know that
To calculate how much fence is needed to enclose the circular pool, find the circumference of the circular pool
The circumference of a circle is equal to
where
D is the diameter of the circle
In this problem we have
Substitute
2)
A: 5
B: 9a & a (from a/6)
C: -5 & ÷4
D: -5 & 9a
I haven't done algebra in a year, so don't think my answers are perfect!
definitions:
term: something separated by a sign/symbol (÷, ×, - +) (a/6 are two separate terms, ÷)
constant terms: variables that can be solved.
unlike terms: terms that don't "go" together, you can't subtract 5 from 9a because there's a variable in the way (eyy that rhymes)
like terms: terms that you can add/subtract/multiply/divide to another term
(another answer to c is 9a & a)
