Answer:
6x^2 - 4y^2 + 2x^2 + 6xy
Step-by-step explanation:
Each of the adjacent sides of the rectangle has a congruent, opposite sides. The perimeter is the sum of the lengths of the 4 sides.
P = 2(3x^2 - 2y^2) + 2(x^2 + 3xy)
P = 6x^2 - 4y^2 + 2x^2 + 6xy
Answer: 64<em>% were girls</em>
Step-by-step explanation:
<em>Add 320 with 180</em>
<em>320+180=500</em>
<em>take 500 and divide it by 320</em>
<em>320/500 = 64</em><em>%</em>
By applying the concept of <em>definite</em> integral and the given restrictions, we conclude that the area of the <em>shaded</em> region in the graph is - 11/12.
<h3>How to find the area of the shaded region in the graph y = x² - 2</h3>
The area below the curve can be found by using <em>definite</em> integrals, which is defined here in this form:
(1)
Now we proceed to calculate the area:
By applying the concept of <em>definite</em> integral and the given restrictions, we conclude that the area of the <em>shaded</em> region in the graph is - 11/12.
<h3>Remark</h3>
The statement is incomplete. Complete form is shown below:
Find the area of the shaded region in the graph y = x² - 2, between x = 0.5 and x = 1.5

Answer:
271.5
Step-by-step explanation:
100-55=45
45% of 187
187*45=8415
8415/100=84.15
84.15 is 45% of 187

Answer:
20 cm is the side of the bigger square.
Step-by-step explanation:
Let one square's side be x,
Then another squares side will be ( x + 5 )
- <em>Formula for square's area: side²</em>
Total area:
- x² + ( x + 5 )² = 625
- x² + x² + 10x + 25 = 625
- 2x² + 10 x + 25 - 625 = 0
- 2x² + 10x - 600 = 0
- 2(x² + 5x - 300) = 0
- x² + 5x - 300 = 0
- x² + 20x - 15x - 300 = 0
- x(x + 20) -15(x + 20) =0
- x = -20, 15
- x = 15
So one square's side is 15 cm
Then the bigger square has:
