Answer:
the answer is $2.17
Step-by-step explanation:
Subtract 8.48 from 4.14 to get 4.34 and then divide that by two to get 2.17. You add 2.17 to 4.14 to get 6.31 and subtract 2.17 from 8.48 to get 6.31.
Hope this helps!

Answer:
a) 22°
Step-by-step explanation:
Side 'a' is the shortest side, so angle A will be the smallest angle. Its value must be less than 60°, eliminating the last two answer choices. The actual value can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (5² +7² -3²)/(2(5)(7)) = 65/70
A = arccos(65/70) ≈ 21.7868°
Angle A is about 22°.
5*3 + 5*4
The 5 must multiply through the parenthesis.
The given equation y = 3x^2+9x is in the form y = ax^2+bx+c
Since a = 3 and b = 9, this means,
h = -b/(2a)
h = -9/(2*3)
h = -9/6
h = -3/2
h = -1.5
is the x coordinate of the vertex (h,k)
As a fraction, the answer is -3/2
In decimal form, that answer is -1.5
(use long division or a calculator to find that -3/2 = -1.5)
Answer:
6 is B since we finding W the variable can't be on both sides of the equation, or else we might end up with w = w.
7 is A because when you graph the equation the slope is 1 and the line crosses the y line at 2.
