Answer:
The GCF is 3.
Step-by-step explanation:
All you do is list out the factors of the numbers and find the greatest factor that they have in common.
Like the GCF of 3 and 9. We list the factors.
Factors of 3:
1, 3
Factors of 9:
1, 3, 9
As we can see, 3 is the GCF because it is the highest factor that the numbers have in common.

Step-by-step explanation:
for #1 it would be the second one.
For #2, it would be the first one
Like terms are the ones that have the SAME variable with SAME exponent. So the ones with x will be considered like terms. The ones with a will also be like terms.
For #1, you would use this fact to combine the like terms. For instance, 3a and -2a are like terms so when they are combined you are left with 1a
Erica tiene *al menos* 50 libros,su mamá le regala un mueble para acomodar los libros,se coloca 11 libros en cada estantería le sobran 8 y si coloca 9 le sobran 4
Determine la cantidad de estantes y de libros que tiene erica
y de qué forma puede acomodarlo para que no sobre ninguno
Erica tiene 85 libros y 9 estanterias, para colocar todos los libros sin que le sobre ninguno, puede colocar 17 libros en 5 estanterias.
¿Cuantos libros tiene?
Primero sabemos que Erica tiene, al menos, 50 libros, entonces si definimos L como el numero de libros que tiene, tendremos:
L ≥ 50.
Si coloca 11 en cada estanteria, le sobran 8, entonces podemos escribir:
L = n*11 + 8 (donde n es un número entero).
Si coloca 9, le sobran 4, entonces:
L = k*9 + 4 (donde k es un número entero).
Entonces tenemos que:
n*11 + 8 = k*9 + 4
n*11 - k*9 + 8 - 4 = 0
n*11 - k*9 + 4 = 0
n = (k*9 - 4)/11
Lo que podemos hacer es evaluar k en distintos valors enteros de tal forma que la solucion de n tambien sea entera. Por ejemplo, si k = 2 tendremos:
n = (2*9 - 4)/11 = 14/11
Notar que en este caso n no es entero, asi que no sirve.
Seguimos, si k = 9 tendremos:
n = (9*9 - 4)/11 = 77/11 = 7
Ambos son enteros.
Entonces Erica tiene:
L = 9*9 + 4 = 85 libros en total.
Y el numero de estanterias sera el maximo entre n y k, que es k = 9, hay 9 estanterias.
Para colocarlos sin que le sobren, puede colocar 17 libros en cada estanteria. Asi con 5 estanterias colocara los 85 libros.

If x = 8 cm, what is the surface area of the geometric shape formed by this net?
A.
384 square cm
B.
1,024 square cm
C.
768 square cm
D.
192 square cm
Answer:
B.
Step-by-step explanation:
Check the picture I have provided for each letter assigned to a shape.
I noted every shape with letters.
A and C are squares and all 3 B's and E are rectangles.
Now we need to calculate the surface area of every shape in order to find out the area of the whole shape.
The surface area of A and C can be found by using the following formula:[tex]s^{2}[/tex] where s means side.
A = 16×16 = 256
C = 16×16 = 256
The surface area of B and E can be found by using the following formula: w×l where w = width and l = length.
A single B = 16×8 = 128
All 3 B's = 128×3 = 384
E = 16×8 = 128
The area of the main shape is = 256+256+384+128 = 1024 square cm.

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
Answer:
b
Step-by-step explanation:
Hi ok heres how I got it:
If the equation is y=3x+2, we just need to plug in each x and y value and see which one doesn't work. Either that, or we can just locate it on the graph.
For example,
10,32
Plugging it in gives us:
32=3(10)+2.
This is correct, meaning that A is NOT the answer.
Continuing testing, and we will find that B is the incorrect pair.
13=3(8)+2 is NOT correct.
13=24 is not equal.
Also,
-13=3(-5)+2 CORRECT,
-22=3(-8)+2 CORRECT AS WELL
Answer:
The ordered pair does not lie on the graph of this function is B. (8, 13)
Step-by-step explanation:
=> y = 3x + 2...i)
By putting the value of x in equation i).. from the options
firstly, putting the value of x = 10
=> y = 3(10)+2
=> y = 32
so, its the ordered pair that lie on the graph
now , putting the value of x= 8
=> y = 3(8) +2
=> y = 24 +2
=> y = 26
its 26, so the ordered pair does not lie on the graph of this function is B. (8, 13)

The total volume of water in the pool =-2 (x-11)(x+5) ft^3
Step-by-step explanation:
a) (2x^2 + 12x + 10) - (4x^2-100)
= 2x^2+12x+10-4x^2+100
= -2x^2+12x+110
b)
Lets simplify first by taking the GCF out:
= -2 (x^2-6x-55)
Now Just simplify by finding the product of a and c
I used -11 and 5 because when you multiply -11x5 you get -55, and when you do -11+5 you get -6.
= -2 (x-11)(x+5) ft^3
Answer:
Given expressions

What is Income Tax?
The part of income a person pays to the government as a contribution to the growth of the nation is called Income Tax.
Sasha earns $16 per hour
Total hours she worked is 2000
Total annual income is $16 *2000 = $32000

Work out the volume of the prism in cm^3 give your answer correct to 3 significant figures
Answer:
The volume of the prism is 243 cm³
Step-by-step explanation:
The volume of the prism is V = B × H, where
B is the area of its baseH is the height of the prism∵ The prism is a triangular prism
∴ Its base is a triangle
∵ The base of it is a right triangle
∴ Its area B = [tex]\frac{1}{2}[/tex] b h, where b and h are the legs of the right angle
→ We have one leg of the right angle and the hypotenuse, so we
must use the Pythagoras Theorem to find the other leg
∵ (5.4)² + h² = (7.8)²
∴ 29.16 + h² = 60.84
→ subtract 29.16 from oth sides
∴ h² = 31.68
→ Take √ for both sides
∴ h = 5.6284989 cm
→ Now find the area of the base
∵ B = [tex]\frac{1}{2}[/tex] (5.4)(5.6284989)
∴ B = 15.196947 cm²
→ Let us use the rule of the volume above
∵ V = B × H
∵ H = 16 cm
∴ V = 15.196947 × 16
∴ V = 243.151153 cm³
→ Round it to 3 significant figures
∴ V = 243 cm³
∴ The volume of the prism is 243 cm³
