Answer:
4x³+2x²+2x
Step-by-step explanation:
9x³-5x³+2x²-5x+7x+4-4
4x³+2x²+2x
The simplified expression for (9x³ + 2x² - 5x + 4)- (5x³ -7x + 4) is
2x( 2x² + x + 1).
We have the Expression,
(9x³ + 2x² - 5x + 4)- (5x³ -7x + 4)
Now, simplifying the expression we get
(9x³ + 2x² - 5x + 4)- (5x³ -7x + 4)
= 9x³- 5x³ +2x² -5x + 7x + 4 - 4
= 4x³ + 2x² + 2x
= 2x( 2x² + x + 1)
Thus, the simplified expression is 2x( 2x² + x + 1).

Step-by-step explanation:
The formula for aera of a triangle is Square =1/2*base*height.

Then we use the formula, the square of the triangle is 1/2*4*4=8
Alejandro bought a bond with a face value of $5,000. The term of the bond is 2 years. He bought the bond at a 4 percent discount from the face value. The bond pays 4 percent annual interest, and Alejandro will receive four semiannual payments. When the bond is redeemed at maturity, the total return (profit) will be $______.00. The total return on investment will be _____%. (Round return on investment percentage to one decimal place.)
1. When the bond is redeemed at maturity, the total return (profit) for Alejandro will be $600.00.
2. The total return on investment will be 12.5%.
What is the return on investment?The return on investment is a profitability measure that shows the rate of an investment's profit versus the cost.
The return on investment can be computed by subtracting the initial investment cost from the terminal value of the investment, then dividing the net return by the initial investment cost, then multiplying it by 100.
Data and Calculations:Face value of bond = $5,000
Price paid for bond = $4,800 ($5,000 x 96%)
Bond discount = $200 ($5,000 x 4%)
Maturity period = 2 years
Interest rate = 4%
Semi-annual interest receipts = $100 ($5,000 x 4% x 1.2)
Total interest receipts = $400 ($100 x 4)
Total return (profit) from the bond = $600 ($400 + $200)
Total return on investment = 12.5% ($600/$4,800 x 100)
Thus, the bond investment yields $600 at the end of the maturity period, which is 12.5% of the initial investment.

Answer:
g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)
Step-by-step explanation:
From the graph, f(2) = 1

So g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)
In 2010, the population of a city was 108,000. From 2010 to 2015, the
population grew by 7.7%. From 2015 to 2020, it fell by 6.1%. To the nearest
100 people, what was the population in 2020?
Answer:
109,200 people
Step-by-step explanation:
First change all the percentages into decimals. Then multiply 108,000 by 1.077, because it is 7.7% of the population, while also including the original population. The product of this is 116,316. Then, if you want to find the percent decrease, it would be something out of 100, so 100-6.1=93.9. Changing that into decimal form, 0.939, and multiplying it by 116,316, you get 109,220, which rounds to 109,200.

the ratio of girls to boys is 6/8
Let the number of boys be x
[tex]\frac{6}{8} = \frac{120}{x}[/tex]
6 x = 120 x 8 = 960

Give an equation in standard form for a line which is perpendicular to -2x + 3y = 7 and has a y intercept of -3.
Answer:
y=-3/2x-3
Step-by-step explanation:
For perpendicular lines,the product of their slopes is -1 this m1•m2=-1
For the given line 3y=7+2x
y=7/3+⅔x,the slope is ⅔
For the unknown line since the y-intercept is -3 then y=mx-3
compare the slopes of both lines
m•⅔=-1
m=-3/2
hence the the perpendicular line has the equation
y=-3/2x-3

Una persona que se dirige desde su casa hasta el colmado hay una longitud de 10 metros , luego la persona regresa a su casa que desplazamiento y distancia usted recorre?
Veremos que la distancia total recorrida es de 20 metros, y el desplazamiento es de 0 metros.
¿Cuanto es el desplazamiento?
Definimos el desplazamiento como la diferencia entre la posición final y la inicial. En este caso sabemos que la persona comienza en su casa, luego va al colmado, y luego regresa a su casa.
Entonces la posicion inicial y la final son la misma, por lo que concluimos que el desplazamiento es 0.
¿Cuanta distancia se recorre?La distancia total recorrida será igual a dos veces la distancia entre la casa y el colmado.
Esta distancia es 10 metros, entonces la distancia recorrida es:
distancia = 2*10m = 20m

Jessica has 300 cm³ of material. She uses 12.6 cm³ to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 3. How much more material does Jessica need in order to make the second prism? Select from the drop-down menu to correctly complete the statement. Jessica needs an additional Choose... cm³ of material to make the second prism.
Jessica needs another 52.8 cm^3 of material to make the other prism.
How much material will she use?For a right triangular prism of base B, height H, and length L, the volume is:
V = (1/2)*B*L*H
Now, we know that the first triangle has a volume of 12.6cm^3, then we can write:
V = 12.6cm^3 = (1/2)*B*L*H
If we dilate the prism with a scale factor of 3, the new dimensions are:
B' = 3B
L' = 3L
H' = 3H
Then the new volume is:
V' = (1/2)*(3B)*(3L)*(3H) = 27*(1/2)*B*L*H
And (1/2)*B*L*H is the original volume, so we can write:
V' = 27*V = 27*(12.6cm^3) = 340.2 cm^3
And she has 300cm^3 and she used 12.6cm^3, so the amount of material that she has left is:
M = 300 cm^3 - 12.6 cm^3 = 287.4 cm^3
Then the amount of material that she needs is:
340.2 cm^3 - 287.4 cm^3 = 52.8 cm^3
So Jessica needs another 52.8 cm^3 of material to make the other prism.
