Subtract the known trinomial from the total sum:
6x2 - 5x + 4 - 4x2 + 3x - 2 = 2X^2 -8x +6
For Q's a to d
a) 2 x 3/4 = 6/4 = 1 2/4 = 1 1/2
<span>b</span>, c and d follow the same pattern
For Q's e to h we use <span>fraction</span> multiplication:
f) 4/5 x 2/3 = 8/15
For Q's <span>i</span> to l we have to change the mixed numbers to top heavy fractions and then multiply:
j) 1 1/2 is equal 3/2 and 1 1/3 is equal to 4/3
Therefore 1 1/2 x 1 1/3 = 3/2 x 4/3 = 12/6 = 2
I hope that this gives you enough information to go on
Vertical angles are identical, so if X is 100 degrees, then Y is also 100 degrees.
half of 100 = 100 / 2 = 50 degrees.

Answer:
4 sides
Step-by-step explanation:
A lot of math is about pattern matching. Here, you're asked if sides are the same length (one side matches another), if there are right angles (square corners), and if the number of angles or sides is 4.
You might make the observations ...
<u>pink</u>: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.
<u>orange</u>: all 4 sides are congruent and at right angles
<u>blue</u>: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.
<u>green</u>: 2 pairs of parallel sides that are the same length--4 sides and 4 right angles. Adjacent sides are different length.

The only feature in common is "4 sides."
