You need to divide 2/5 and 3/4. First, you need to do "Keep Change Flip". We do this by keeping 2/5 the same, changing the division sign to a multiplication sign and flipping 3/4 to make 4/3. Lastly, you add them up and get your answer.
2/5 ÷ 3/4
2/5 X 4/3 = 8/15
No 5/8 is a rational numbe.
(7x^2-2) - (2x^2 - 5x + 3)
Answer:
5(x^2+x-1)
First, we circumscribe a rectangle about the parallelogram as shown in the figure. The size of this rectangle is 10 by 6 clearly.
Between the rectangle and the parallelogram 4 triangles are formed, 2 by 2 congruent. We are going to remove the area of these 4 triangles from 60 (the area of the rectangle) and thus get the area of the parallelogram.
Note that one of the triangles has side lengths 4; 4. Thus, the area of this triangle is (4*4)/2=16/2=8 (square units.)
Each of the other two non-congruent triangles to the above have sides of length 6;2, so the area of each is (6*2)/2 =6 (square units.)
Thus, the area of the parallelogram is 60-8-8-6-6=60-16-12=60-28=32 (square units.)
Answer: 32 (square units.)
