P=AMOUNT
Answer:
3/10
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
i) (a + b)^2 = a^2 + 2ab + b^2
= (x + y)^2 + 2(x + y)(x - y) + (x - y)^2
= x^2 + 2xy + y^2 + 2(x^2 - y^2) + x^2 - 2xy + y^2
= x^2 + 2x^2 + x^2 + y^2 - 2y^2 + y^2 + 2xy - 2xy
= 4x^2.
ii) (a - b)^2 = a^2 + b^2 - 2ab
= (x + y)^2 + (x - y)^2 - 2 - 2(x^2 - y^2)
= x^2 + 2xy + y^2 + x^2 - 2xy + y^2 - 2x^2 + 2y^2
= x^2 + x^2 - 2x^2 + y^2 + y^2 + 2y^2 + 2xy - 2xy
= 4y^2.
Answer: 123.5 in^2
Step-by-step explanation: The formula for the area of a trapezoid is a+b/2 x h. In other words, base 1 plus base 2 divided by 2, and multiplied by the height. Plug in the numbers. The equation is:
6+7/2 x 19 = 123.5.
Since you are finding the area, the answer would be in inches squared. The answer is 123.5 in^2.
Answer:
yes because it just reflected, the shape didn't get smaller or bigger. it stayed the same
