Answer: only true statement is ---The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right
Step-by-step explanation:
Let Brain and Damien both scored x while Chris scored y then
According to the first relation
where x and y are less than or equal to 20 .
For y=20 , x=19 possible value
According to the second relation
where x and y are less than or equal to 20 .
For y=20 , x= 23 not possible
so only true statement is ---The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right

Answer: 200 mm
Step-by-step explanation:
The perimeter of rectangle is given by :-
, where l is length and w is width of the rectangle.
Given : Two sides of a rectangle are 4 cm in length. The other two sides are 6 cm in length.
The perimeter of the rectangle will be :_
We know that 1 cm = 10 mm
Therefore, perimeter of the rectangle =
We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.
So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:
So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.
