Answer:
x³/4z²
Step-by-step explanation:
Invert and multiply:
48x^5y²/12z^5 x z³/16x²y²=
(48x^5y²)(z³)/(16x²y²)(12z^5)
the y² cancel out
48÷16=3 (on top)
x^5÷x²=x³
12z^5/z³=z²(on bottom)
This leaves a 3x³ on top and 12z² on the bottom. 3÷12=4 (on bottom):
3x³/12z²
x³/4z²
Answer:
14 meters ^2
Step-by-step explanation:
formula: A=(h<em>b*</em>b)/2
A=(4*7)/2
A=(28)/2
A=14
A scaled version means that our leading coefficient will change. Let's set up an equation to find our leading coefficient, a.
g(x) = a * x^2
Now that we have our equation, we need a point that is on g(x). The point given is (4,8). Let's use that point and plug x and y into our equation so that we can solve for a.
8 = a * (4)^2
8 = a * 16
a = 1/2
All that's left to do is plug in our a value into g(x).
g(x) = 1/2 x^2
Hope this helps!! :)
D. (5/9v - 5/9)
<u>Step-by-step explanation:</u>
(2/9v)- (-1/3v+ 5/9)
Since it is subtraction, we have to change the sign of the second expression that is after the (-) sign.
= (2/9v + 1/3v - 5/9)
Since we have different denominators, we have to take LCM of 3 and 9 as 3, so the expression becomes,
= (2/9v + 3/9v - 5/9)
= (5/9v - 5/9)
