The side of a square was reduced by 3 in and the other side was enlarged by 5 in. The area of a new rectangle is 9 square inches. Find the side of a square

Answers

Answer:

4

Step-by-step explanation:

Give the other guy a 5 star my dude lol

The square has a property of having all the sides equal. The rectangle on the other hand has its opposite sides equal. The larger side of the rectangle is called length and the smaller side is called breadth. The area of rectangle is the product of length and breadth i.e.

[tex]\rm Area\:of\:rectangle = Length\: \times Breadth[/tex]

The side of square for the given question is [tex]4\rm \: inches[/tex].

Calculation:

Let the side of square be [tex]\rm x[/tex]

Given:

Area of rectangle is 9 square inches.

Side of square is reduced by 3 and other side is enlarged by 5. Therefore, dimensions of the rectangle will be:

[tex]\rm Breadth = x - 3\\\\Length = x + 5[/tex]

[tex]\rm Area\:of\:rectangle = Length\: \times Breadth\\\\9 = (x + 5)(x -3)\\\\9 = x^2 + 5x -3x -15 \\\\9 = x^2 +2x - 15 \\\\0 = x^2 +2x-15-9\\\\0 = x^2+2x-24\\\\[/tex]

On factoring the equation:

[tex]\begin{aligned} \rm x^2 + 2x -24 &= 0\\\\x^2 + 6x - 4x - 24 &= 0\\\\x(x+6)-4(x+6) &= 0\\\\(x+6)(x-4)&=0\end[/tex]

On equating [tex]\rm (x +6)[/tex] and [tex](x-4)[/tex] with 0 we get:

[tex]x = -6\\\\x=4[/tex]

Since side of square cannot be negative, [tex]x = 4[/tex] is the only correct value.

Therefore the side of square is [tex]4 \:\rm inches[/tex].

Extra Example 3: Hazel has $23.28 in her purse. She has $5.60 more than Nixon.
Paul says that Nixon has $28.88. Yolanda says that Nixon has $17.68. Who is
correct?

Answers

Answer:

Yolanda is correct.

Step-by-step explanation:

If Hazel has $23.28 and $5.60 more than Nixon, then Nixon will have $17.68 because 23.28-5.60 is 17.68.

The only way Paul would be right is if Nixon has $5.60 more than Hazel because 23.28+5.60 is 28.88.

Simplify fully 4a sqaured +8a +2 I-a squared +9a -3

Answers

Answer:

The simplified expression is: [tex]3a^2 + 17a - 1[/tex]

Step-by-step explanation:

We are given the following expression:

[tex]4a^2 + 8a + 2 - a^2 + 9a - 3[/tex]

We can fully simplify the expression by combining the like terms. So

[tex]4a^2 + 8a + 2 - a^2 + 9a - 3 = 4a^2 - a^2 + 8a + 9a + 2 - 3 = 3a^2 + 17a - 1[/tex]

The simplified expression is: [tex]3a^2 + 17a - 1[/tex]
