X^4 - x^2 + 9 - (x^3 + 3x^2 + 12) =
x^4 - x^3 - 4x^2 - 3
Answer:
sqrt (65) = 8.062 units = x
Step-by-step explanation:
use Pythagorean theorem for a right triangle
a ^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
4^2 + x^2 = 9^2
x^2 = 9^2 - 4^2
x^2 = 65
x = sqrt 65
Answer:780,780 I don't know if it is right though.....
Step-by-step explanation:
Answer: A. 64.5 in. sq
Step-by-step explanation:
For finding the area we can split the E into rectangles and square. ( Shown below )
Hence, by the below diagram,
The area of the given figure = Area of rectangle having dimension 2.5 in × 13 in + 2× (Area of the rectangles having dimension 4 in × 3.5 in ) + Area of a square having side length 2 in,
= 2.5 × 13 + 2( 4 × 3.5 ) + 2 × 2
= 32.5 + 2( 14 ) + 4
= 36.5 + 28
= 64.5 square inches
Hence, the complete area of the given figure is 64.5 square inches.
⇒ Option A is correct.
