Yessss that should be correct
2x² + 6x - 3 + 2x³ - 3x + 2
Combine like terms
2x³ + 2x² + 6x - 3x - 3 + 2
Final answer:
2x³ + 2x² + 3x - 1
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
Answer:
c) 25 degrees
Step-by-step explanation:
85 - 30 - 30 = 25
