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
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].

the mathematical statement below are all linear inequalities in two variables EXCEPT:
a.)3y<10-2y
b.)2x-y>6
c.)3x-5y_>15
d.)23_<3m-2n
Answer: Option a: 3y < 10 - 2y
Step-by-step explanation:
A linear inequality is something that can be written as:
y > a*x + b
or
y < a*x + b
So we need to see which inequality of the given ones CAN'T be written in this way.
a) 3*y < 10 - 2*y
Here we can see that we have only one variable, so this can not be a linear inequality.
b) 2*x - y > 6
We can rewrite this as:
y < -6 + 2*x
Then this is a linear inequality.
c) 3x-5y ≥ 15
This can be rewritten as:
y ≤ (3/5)*x - 15/5
Then this is a linear inequality.
d) 23 ≤ 3m - 2n
This can be rewritten as:
m ≥ (2/3)*b + 23/3
This is a linear inequality.
Then the option that is not a linear inequality in two variables is option a.

Answer:
A. Distance KL = 7.36 m
B. Height ML = 4.25 m
C. The maximum height is 6.96 m
Step-by-step explanation:
A. Determination of distance KL
Hypothenus = KM = 8.5 m
Angle θ = 30°
Adjacent = KL =?
Cos θ = Adjacent / Hypothenus
Cos 30 = KL / 8.5
0.866 = KL / 8.5
Cross multiply
KL = 0.866 × 8.5
KL = 7.36 m
Thus, the distance is 7.36 m
B. Determination of height (ML)
Hypothenus = KM = 8.5 m
Angle θ = 30°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 30 = ML /8.5
0.5 = ML / 8.5
Cross multiply
ML = 0.5 × 8.5
ML = 4.25 m
Thus, the height is 4.25 m
C. Determination of the maximum height.
Hypothenus = KM = 8.5 m
Angle θ = 55°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 55 = ML /8.5
0.8192 = ML / 8.5
Cross multiply
ML = 0.8192 × 8.5
ML = 6.96 m
Thus, the maximum height is 6.96 m

Math help!
Answer:
14.42cm and 59 degrees
Step-by-step explanation:
Use the pythagorean theorem to find the length of AB
24^2 + AB^2 = 28^2 ---> 14.42
Do arcsin(24/28) to get 59 degrees since 24 is the opposite and 28 is the hypotenuse.
Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties
water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water.
Three minutes later, the tank contains 5 gallons of water.
Type your answers in the boxes below.
C. How many minutes before Jada arrived was the water tank completely full?
Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds
