Answer:
6
Step-by-step explanation:
We want to evaluate:
8a-1+0.5b
When a=1/4 and b=10.
We simply substitute the given values of as and b into the given expression,
The value of the expression is 6 for the give values of a and b.
the value of cos 15 is √3+1/2√2
explanation
cos (45-30)
=cos45*cos30+sin45*sin30
=1/√2 * √3/2 + 1/√2 * 1/2
=√6/4 + √2/4
=√6 + √2/4
=√3+1/2√2
Answer:
1
Step-by-step explanation:
I dont know how to explain but thats what I think
Answer:
16x^2 -36 does factorise
x^2 -6x +36 don't factorise
x^2 -4x +4 does factorise as (x−2)(x−2)
36x^2 +108x +819 does factorise as (2x+3)(2x+3)
25x^2 +30x +36 don't factorise
Hope this helps!
6 < c < 20,
Of course if you knew the triangle was a right triangle you could use the Pythagorean theorem to directly get the size of the third side.
