Answer: n= 15
Step-by-step explanation:
Perimeter is just adding all the lengths of all the sides. So You already have the two sides which are 28 each. If you add those two is 56. So now you would subtract 56 from 86 since 86 is your total.
86 (perimeter) -56 (total of two sides)
This gives you 30
Since you have two equal sides left, you will divide 30 by two and that gives you 15
So, n= 15
Answer:
3x+4y+7y = 3x + 11 y
Step-by-step explanation:
We need to simplify the given expression i.e.
3x+4y+7y
We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
So,
3x+4y+7y = 3x + 11 y
Hence, the final simplification should be 3x + 11 y.
<span>y= 2*3-4x;
differentiate with respect to t we get dy = -4xdt; -- eqn 1
given dt = 4 substitute in eqn 1 we get , dy =-4 x( 4) = -16x; --eqn2
given x=1 then sub then the value of x in eqn 2 we get dy = -16(1)=-16
ie Ans dy = -16</span>
You didn’t give us enough info but I will say C.
Tax is going to be the price that you see before checking out and getting your total. not sure if this is what you're asking but i hope it helps
