The correct choice is A. When something is being increased by a percentage, you add the percentage to 100%, so you add 35% to 100% to make a decimal of 1.35.  Every year the initial value of 590 will be increased by 35%. so the correct choice is A.

If (x + y)^2 = 105 and x^2 + y^2 = 65, what is the value of xy?
lesya692 [45]
\boxed { \boxed {(a + b)^2 = a^2 + 2ab + b^2}}

(x + y) ^2 = 105

x^2 + 2xy + y^2 = 105

x^2 + y^2  + 2xy = 105


\text{Given that } x^2 + y^2 = 65,

65 + 2xy = 105

2xy = 105 - 65

2xy = 40

xy = 20

\boxed { \boxed {\text{Answer: xy = 20}}}

Use elimination to solve the system of equations. 5x-2y=-3 4x-2y = -6
Effectus [21]

Answer:

x=3, y=9

Step-by-step explanation:

5x-2y=-3

4x-2y=-6

Then:

solve for y:

-2y=-6-4x

y=3+2x

Substitute y into either equation:

4x-2(3+2x)=-6

4x-6-4x=-6

-6=-6, use other equation

5x-2(3+2x)=-3

5x-6-4x=-3

x-6=-3

x=3

then:

y=3+2(3)

y=9

Alex has 520 yards of fencing to enclose a rectangular area.
Pavlova-9 [17]
<span>Perimeter =2w+2L= 520.
We can solve this by understanding that the area is maximized by a square
Therefore L=w.

p=2w+2w=520=4w
w=130

Area
 
A=wL=130(130)= 16900 square yards</span>
