Answer:
4/15
Step-by-step explanation:
2x/5-3y/2=7
<em>Multiply all terms by the lcd.</em>
10(2x/5) + 10(-3y/2) = 10(7)
<em>Cross cancel.</em>
2(2x)+ 5(-3y) =70
<em>Simplify.</em>
4x -15y = 70
<em>Subtract 4x from both sides.</em>
-15y = -4x +70
<em>Divide by -15 on both sides.</em>
y= 4/15x -24/3

Answer:
Step-by-step explanation:
The sum of two even numbers is an even number
Substitute the x for 6 then 10,
8(6)+40 8(6+5)
8(10)+40 8(10+5)
then calculate
<h2>
Answer:</h2>
x²+8x+16
<h2>
Step-by-step explanation:</h2>
So it is a square with a side of x+4 as it is written in the question.
You calculate the area by (x+4)(x+4)
That is x²+8x+16
The picture is just for a visual representation. If you wouldn't want to multiply as I showed above, you would just add like terms.
x²+4x+4x+16
x²+8x+16
