The first step in solving this is to substitute x with 3 and y with 2, so that
becomes
Then simply solve using the order of operations.
First exponents (there are no parentheses)
Then multiply and divide
And finally add and subtract
Therefore the value <span>of 1/3 x^2 + 5.2y when x=3 and y=2 is 13.4</span>

Answer:
p=1/4 or 0.25
Step-by-step explanation:
2p+3=5-6p Subtract 2p from both sides.
<u>-2p -2p</u>
3=5-8p Subtract 5 on both sides.
<u>-5 -5</u>
-2=-8p Divide by -8 on both sides.
<u>/-8 /-8</u>
1/4=p or (as a decimal) 0.25=p
Hope this helps you out!! Have a great day c:
Answer:
The factored version of the given equation is going to be (3x² + 4y)(x + 5)
Step-by-step explanation:
<em>3x³ + 15x² + 4xy + 20y</em>
First, you break down 3x³. You can do this by finding the common factor of 3x³ and 15x². You can add the x to the other parentheses because x times x² equals x³
<em>(3x² + )(x + 5)</em>
Now, we break down 4xy by finding the common factor of 4xy and 20y.
<em>(3x² + 4y)(x + 5)</em>
So, the factored version of the equation above is (3x² + 4y)(x + 5)
2 because 4/2=2 hope it works
