X²-8x=3
x²-8x+16=3+16=19
(x-4)²=19
x-4=±√19
x=4±√19
x=8.3589 approx or x=-0.3589 approx {4-√19,4+√19} or {-0.3589,8.3589}
Answer:
-240
Step-by-step explanation:
A) JL and JK
Because you must always start from top to bottom and left to right.
Answer:
C: (4, 8)
Step-by-step explanation:
Rewrite the given equation x² - 8x = -y² + 16y - 44 in std. form:
x² - 8x + 16 - 16 + y² - 16y + 64 = 64 - 44, or
(x - 4)² + (y - 8)² = 64 - 44 + 16
Comparing this to (x - h)² + (y - k)² = 6²
we see that h = 4 and k = 8. The radius is 6. The center is at (4, 8) (Answer C).
The formula of the volume of a pyramid is 1/3 b*h where b is the area of the base which in this case is a square and has a formula of s^2. Hence doubling the side would make the new figure having four times the original volume. Answer is true. In 2, if all three dimensions of a rectangular prism double, then the volume will be 2^3 or 8 times larger. Answer is false.
