I believe it should be ∆LKD because the parts should correspond with each other. D is a right angle in the first triangle and appears in the middle, so since K is the right angle of the second, it should also go in the middle.
I believe this is proven by HL because both hypotenuses are congruent, as is a pair of legs, and they are both right triangles.
All real numbers or is it multiple choice
<span>f(x)=x^3-4x^2+2x+4, we know that f(2)=8-16+4+4=16-16=0
and we can write f(x)= (x-2)Q(x) so Q(x) = f(x) / (x-2)=x²-2x-2
</span><span>x²-2x-2=0 delta = (-1)²- (1).(-2) =1+2=3
</span>x=1-sqrt3 or <span>x=1+sqrt3
finally the zeros are x=2, </span>x=1-sqrt3 or <span>x=1+sqrt3 </span>
To solve this question, we first need to convert both of these values into mixed numbers. 5
becomes
and 4
becomes
. Now we have to find a LCD. An LCD for 4 and 8 is 8, so now we have to change
into something over 8.
becomes
when you multiply the fraction by the form of 1
. 34 + 43 = 77, so our answer is 77/8 which simplifies to
9 
.
