Use the grouping method to factor the polynomial below completely.
x3 + 2x2 + 3x + 6
A. (x2 + 2)(x+3)
B. (x2 + 3)(x+3)
C. (x2 + 2)(x + 2)
D. (x + 3)(+ 2)
Answer:
D. (x2 + 3)(x+ 2)
Step-by-step explanation:
When x3 + 2x2 + 3x + 6 is grouped, it is simplified to (x2 + 3)(x + 2).

If a triangle has sides of 8,11, and 13. Is it a right triangle?
If a² + b² = c², then the triangle is right.
So we have (8)² + (11)² ? (13)²
(8)² is 64, (11)² is 121, and (13)² is 169.
So we have 64 + 121 ? 169
64 + 121 is 185 and we can see that 185 > 169.
This triangle would not be a right triangle.
In fact, it would be an acute triangle.
So no, it's not a right triangle.
The diagram represents an 11 cm by 6 cm rectangular
What is the answer?
Answer:
See below.
Step-by-step explanation:
If you need the area it is 11 * 6 = 66 cm^2.
The perimeter is 2*11 + 2*6 = 34 cm.
The diagram shows squares 1, 2, and 3 constructed on the sides of a right

the shape of a toy cylinder has a radius of 5cm and height of 8cm on top a hemisphere of radius 5cm , calculate the volume of the toy
someone should pls help me
Answer:
890.1 cm^3
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr^2h
Filling in the given numbers, we find the volume of the cylinder to be ...
V = π(5 cm)^2(8 cm) = 200π cm^3
__
The volume of a hemisphere is given by the formula ...
V = (2/3)πr^3
Filling in the given radius, we find the hemisphere volume to be ...
V = (2/3)π(5 cm)^3 = 250π/3 cm^3
__
The total volume of the toy is presumed to be the sum of these volumes, so is ...
toy volume = (200π cm^3 +250π/3 cm^3) = 850π/3 cm^3
toy volume ≈ 890.1 cm^3

9. A rectangle is located on a coordinate plane. If the ordered pair (t, u) represents a vertex of this rectangle, which algebraic representation describes the effect of translating the rectangle 8 units up and 3 units left? (t, u) → (t + 3, u + 8) (t, u) → (t – 3, u + 8) (t, u) → (-t – 3, u + 8) (t, u) → (t + 8, u – 3)
Up is the y value and left is the x value.
In the point ( t,u) t is the x value and u is the y value.
Moving to the left, you subtract the value and moving up you add the value.
The answer would be (t, u) → (-t – 3, u + 8)

Multiply first two values in brackets:
5 x 4 = 20
Multiply the outside values in the brackets:
-x * 5 = -5x
Multiply the inside terms:
-x * 4 = -4x
Multiply the last terms:
-x * -x = x^2
Place all values together:
x^2 - 5x - 4x + 20
Simplify it:
x^2 -9x + 20

what will be the another acute angle of right angle triangle is its one acute angle is 30 degree
Answer:
60°
Step-by-step explanation:
90+30=120°
180-120=60°
Step-by-step explanation:
all sides of a triangle = 180
all sides of a triangle = 180
So 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x
so equation forms like
180 = 90+30+x
180 =120+x
180-120 =x
60 =x
SO THE ANSWER WILL BE 60°
HOPE IT WILL HELP YOU ☺️

A cylinder-shaped water tank is 160 cm tall and measures 87.92 cm around.
What is the volume of the water tank?
Enter your answer as a decimal in the box. Use 3.14 for π.
Answer:
Step-by-step explanation:
The volume formula for a cylinder is
[tex]V=\pi r^2h[/tex]
In order to find the radius we need to use the circumference we were given. The formula for the circumference is
[tex]C=2\pi r[/tex]
Filling in the info about the circumference value of 87.92:
[tex]87.92=2(3.14)r[/tex] or
87.92 = 6.28r so
r = 14
Now that we know the radius we can fill in the volume formula:
[tex]V=(3.14)(14)^2(160)[/tex] and
V = 98470.4 cm cubed

Simplify (2x-3)(2x-2)
Answer:
We get the final answer of -4x + 6
Step-by-step explanation:
Let's simplify step-by-step.
2x −3(2x−2)
Distribute:
= 2x+ (−3)(2x) + (−3)(−2)
= 2x+ −6x + 6
Combine Like Terms:
= 2x + −6x + 6
= (2x + −6x) + (6)
= -4x + 6
Em uma perfumaria, um cliente pode montar um kit formado por um sabonete, um hidratante e um perfume. A loja possui 5 opções de sabonete, 8 de hidratante e 4 de perfume. Quantos kits diferentes um cliente poderá formar na perfumaria?
Answer:
The customer can form 160 different kits in the perfumery
Step-by-step explanation:
Here, we are interested in knowing the number of different kits a customer can form in the perfumery.
Now since each kit contains 1 each of moisturizers, soaps and perfume, what will happen is that we are going to select one each of the options
This means we shall be selecting 1 out of 5 soaps, 1 out of 8 moisturizer and 1 out of 4 perfumes
Mathematically, the number of ways we can select r items out of a total of n can be calculated as nCr
Applying this in the case we have;
It would be;
8C1 * 5C1 * 4C1
where
8C1 = 8, 5C1 = 5 and 4C1 = 4
Thus the number of options we have will be
= 8 * 5 * 4 = 40 * 4 = 160 kits
Responda:
O cliente pode formar 160 kits diferentes na perfumaria
Explicacao/etapas:
= 8 * 5 * 4 = 40 * 4 = 160 kits

on a piece of paper,graph this system of inequalities then determine which answer choice matches the graph you drew and identify the number of solutions
y<3/2x-2
y<3/2x -8
Answer: b infinite number of solutions (blue and purple)
Step-by-step explanation:
There will be multiple solution for both inequality.
What is inequality?Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.
According to the question
y<3/2x-2 ---------- (1)
y<3/2x -8 -----------(2)
to take out points we have to take (1) as y= 3/2x-2
x y
-4 -8
-2 -5
0 -2
2 1
4 4
6 7
same for (2) we take y=3/2x -8
x y
-2 -11
0 -8
2 -5
4 -2
6 1
Then we plot our graph which is shown in sheet attached
According to the graph we can see that they both are parallel to each other now we will shade left hand side of line as per the inequality
when we shade we will observe that points left side of equation (2) are common in both .
Hence, there will be multiple solution .
