Answer:
two cost 5.6 dollars
Step-by-step explanation:
8.4 / 3=2.8$
2.8*2=5.6$
The solution is 2sqrt77/77. You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9). Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77. I rationalized the denominator to get that result up there.
Answer:
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy
Answer:
yes
Step-by-step explanation:
Well, if 'y' has zeros at x=6 and x=-8,
then 'y' must be the product
y = (x - 6) (x + 8)
Perform the multiplication to get the quadratic function:
y = x² + 2x - 48
