Answer:
A)
A1= 64
A2= 40
B)
P= 56(of whole shape)
Step-by-step explanation:
A squares area is a side squared so 8^2= 64, and it is also shown that a side of the square is the base of the parallelogram. The area of a parallelogram is b*h so (square side)(8) * height(5)= 40.
Since a parallelograms opposite sides are congruent, 8+8=16, and the other two sides need to be congruent and equal to 40-16(24), therefore the sides are both 12.
Then to calculate the perimeter just count up the side lengths, 8+8+8+12+8+12=56
(3x^5 + 8x^3) - (7x^2 - 6x^3) = 3x^5 + 8x^3 - 7x^2 - 6x^3 = 3x^5 + 2x^3 - 7x^2
The width (x) is 18. I wrote it out in case you need to show your work. Your welcome.
Answer:
x = 7
y = 5
Step-by-step explanation:
6x - 2y = 32
4x - 2y = 18
2x = 14
4x - 2y=18
x = 7
4 * 7 - 2y = 18
x = 7
28 - 2y = 18
x = 7
2y = 10
x = 7
y = 5
there is only 1 solution for this equation is (7;5)
Done :))
