All four sides of the original square have length s.
Adding 3 to s results in s+3, the length of the resulting rectangle.
Subtracting 3 from s results in s-3, the width of the rectangle.
The area of the rectangle is (s+3)(s-3) = s^2 - 9 = 27,
and therefore s^2 = 36, and s = 6 square units.
<h3>Answer:</h3>
x=5, y=2
<h3>Explanation:</h3>
The second equation gives an expression for x that can be substituted into the first equation.
... (y+3) +y = 7 . . . . . .substitute y+3 for x
... 2y + 3 = 7 . . . . . . . colect terms
... 2y = 4 . . . . . . . . . . subtract 3 from both sides
... y = 2 . . . . . . . . . . . . divide both sides by 2
Using the expression for x, we can find its value.
... x = y + 3
... x = 2 + 3 . . . . . . . . . substitute for y
... x = 5
The solution is (x, y) = (5, 2).
Answer:
we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Step-by-step explanation:
Given the expression
SECOND STEP
subtract 3 from the right-hand side as well as on the left-hand side
SOLVING THE REMAINING COMPLETE COMPRESSION
Divide all parts by -2
- Please note that multiply or divide an inequality by a negative number flips the inequality sign.
so the expression becomes
Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
No if I’m correct it should be 40 degrees
