if you're trying to solve for x, and it is equal to zero, then it would be -3. plug it in and it would all cancel out
Reason F should be "CPCTC" which stands for "corresponding parts of congruent triangles are congruent". Its like saying "if two houses are identical, then the front doors should be the same". The houses in the analogy are the triangles, while the front doors are the corresponding parts. So if triangle DEC is congruent to triangle BEC, then the corresponding parts angle DEC and angle BEC are congruent.
===========================================
Reason H is "linear pair postulate" which says that if two angles form a linear pair then they are considered supplementary. This is simply what "supplementary" means. The two angles add to 180 degrees. A "linear pair" is where you have two angles that are adjacent and the angles combine to form a straight angle (180 degrees).
===========================================
Side note: It seems like some of this proof has been cut off. There should be more lines to this proof because the last line is always what you want to prove. In this case, the thing we want to prove is "angle DEC and angle BEC are right angles" so that should be the last statement.
Let T be total number of milligrams of vitamin C in our salad.
We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.
Let us find how much mg of vitamin C our each ingredient of salad will have.
We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.



To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.
Therefore, our desired expression will be
.
It should just be 2y. Hope it helps.
<h2>Vertical distance gained from takeoff is 493.72 ft</h2>
Step-by-step explanation:
Refer the figure.
Horizontal distance = AB = 2800 ft
Angle = ∠B = 10°
We need to find AC that is h.
We have

Vertical distance gained from takeoff = 493.72 ft
