Answer:
[tex]642in^{2}[/tex]
Step-by-step explanation:
So, the area of the rectangular box is [tex]684in^{2}[/tex] which means that that's how much wrapping paper you require.
Formula for total surface area:
[tex]2(lb+bh+lh)[/tex]
Wherein:
l = length
b = breadth
h = height
Substituting the following values,
[tex]2[(19*12)+(12*3)+(3*19)][/tex]
= 642

Answer:
Step-by-step explanation:
9. (x+12)(x-3)/(x-3)= x+12
10. (x-15)(x+3)/(x+3)= x - 15
11. (x-8)^2/(x-8)= x - 8
12. (x-30)(x+3)/(x+3)= x - 30

x^ -10x+ what?
Answer:
25
Step-by-step explanation:
So basically remember that:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
so far you have that
[tex]a^2 = x^2\\2ab = -10x[/tex]
So if 2ab = -10x and a = x, that means 2xb = -10x so b = -5.
It's kind of confusing to think of it like that, but all that means is that the equation is:
[tex](x - 5)^2[/tex]
which would simplify to
[tex]x^2 - 10x + 25[/tex]
so the blank is 25

The drawing shows a heart-shaped figure. The heart is composed of a square and two semicircles. The semicircles have the center in the middle of two of the sides.
a) Set up a formula to calculate the area of the heart.
Answer:
Area = πx² + x² or x²(π + 1)
Step-by-step explanation:
The area of the heart = area of a circle + area of the square
Note:
1. The 2 semicircles makes 1 full circle
2. The diameter of the circle = the side length of the square
Thus:
Area of the heart = πr² + s²
Where,
r = x
s = x
Formula for area of the heart = π(x²) + x² = πx² + x²
Area = x²(π + 1)

What are the missing angles? What is the relationship between the measures of supplementary angles?
Answer:
6=100°
8=80°
7=100°
9=80°
Step-by-step explanation:
If 6 is 100°
in a straight line theres 180 degrees
180-100=80°
8 is 80°
opposite 6 to 7 there are parallel corresponding angles meaning the angle opposite it will be the same. 8 with 9.

Find the value of x in degrees
Answer:
x=37
Step-by-step explanation:
angles inside a triangle add up to 180
add all angles equal to 180
(x+10)+(3x-5)+(x)=180
remove parenthesis, combine like terms
5x-5=180
add 5 both sides
5x=185
divide by 5
x=37
angles: 37, 47, 106

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:
530.66 square cm
Step-by-step explanation:
A=pi*r^2
A=pi*13^2
A=530.66
Answer:
A = 530.91 [tex]cm^2[/tex]
Step-by-step explanation:
The formula to find the area of a circle is ([tex]A = (pi)r^2[/tex]), where ([tex]A[/tex]) represents the area of the circle, ([tex]pi[/tex]) represents the value ([tex]3.1415...[/tex]), and ([tex]r[/tex]) represents the radius of the circle.
