Answer:
208 history books
124 chemistry books
Step-by-step explanation:
Let a = total number of books
b = number of history books
c = number of chemistry books
a = b + c
We know that a is equal to 332 and c = b - 84
Let's substitute this value to our equation and solve for b first. Now we get:
332 = b + ( b - 84)
332 = 2b - 84
332 + 84 = 2b
416 = 2b
b = 208
Now we can solve for c
332 = 208 + c
332 - 208 = c
c = 124
Now let's check
a = 332
b = 208
c = b - 84 = 208 - 84 = 124

Answer:
Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.
Step-by-step explanation:
Considering the quadrilateral with vertices
Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.
From the figure a, it is clear that the quadrilateral has
- Two pairs of sides
- Each pair having two equal-length sides which are adjacent
- The angles being equal where the two pairs meet
- Diagonals as shown in dashed lines cross at right angles, and one of the diagonals does bisect the other - cuts equally in half
Please check the attached figure a.
