Answer:

40

Step-by-step explanation:

Area of the triangle is 24

Area of rectangle is 16

16+24=40

So to find Area, use the formulas:

A = Length x Height       (Rectangle)

A = Base x Height / 2     (Triangle)

Rectangle:

A = L x H

A = 8 x 2 = 16

Triangle:

A = B x H /2

A = 8 x 6 / 2 = 48/2 = 24

16 + 24 = 40

The Composite Figure Area is 40in.

\bf \textit{difference and sum of cubes} \\\\ a^3+b^3 = (a+b)(a^2-ab+b^2) ~\hfill a^3-b^3 = (a-b)(a^2+ab+b^2) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \boxed{a^6+b^6}\implies a^{2\cdot 3}+b^{2\cdot 3}\implies (a^2)^3+(b^2)^3 \\[2em] [a^2+b^2] [(a^2)^2-a^2b^2+(b^2)^2]\implies \boxed{(a^2+b^2)(a^4-a^2b^2+b^4)}

about the second one... well, is a "fait accompli" that using the pythagorean theorem, if x = 8 and y = 5, the hypotenuse must be √(8² + 5²) = √(89), which is neither of those choices.

5, 8, 13 are no dice, namely 5² + 8² ≠ 13

25, 64, 17 is are no dice too, because 25² + 17² ≠ 64²

however, 5,12 and 13 are indeed a pythagorean triple

also is 39, 80, 89.

when looking for a pythagorean triple, recall that c² = a² + b².

so the longest leg is the sum of the square of the small ones.

so what you'd do is, check the small legs, square them, add them up, if they're indeed a pythagorean triple, they "must" add up to the longest leg.

A: 25.12 (26 if your rounding)

B: You have to multiply R by 2 then by pi (3.14)

C: 10.5 (11 if your rounding)

Step-by-step explanation:

For a: A circle's circumference is its diameter multiplied by pi (3.14) To get the diameter you would multiple the radius by 2. Therefore your answer being 25.12 (Round to 26 if you want)

For c: Divide 65 by pi then that answer by two.
