Answer:
√7/22
Step-by-step explanation:
p=√7
b=22 ( R as reference)
tanR=p/b
√7/22
You can round yourself.
A. the domain is all real mumber exept 6
x-6=0
x=6
you solve the denominator for x to find the domain.
B. the range is all real numbers exept 0.
to find the range you have to graph it.
B. 8 the radius is half the diameter
Answer : 2 necklaces are blue
8 * 1/4 = 8/4
8/4 = 2
The value of the coefficient of the xy term when the expression is multiplied out and the like terms are collected is 2bc
<h3>Factoring expressions</h3>
Given the expression below;
( ax+ by ) ( cx + dy)
Expand to have:
<u>( ax+ by ) ( cx + dy) =</u> acx² + adxy + bcxy + bdy²
If ad=bc, the expression becomes;
( ax+ by ) ( cx + dy) = acx² + 2bcxy + bdy²
Substitute the value of ac and bd to have;
( ax+ by ) ( cx + dy)= 18x² + 2bcxy + 50y²
Hence the value of the coefficient of the xy term when the expression is multiplied out and the like terms are collected is 2bc
