Answer: 1 year

Step-by-step explanation:

1. Make an equation for both Types in standard y = mx + b form, with “b” being how tall the tree already is (so b for Type A will be 9, and b for Type B will be 2). Let “m” be equal to how many inches each tree grows per year (m for Type A will be 17, m for Type B will be 24)

2. Now you have the equations!
Type A: y = 17x+9
Type B: y = 24x+2

3. The problem is asking for how many years (represented by “x”) it will take for the trees to be of equal height, so set both of the equations equal to each other
17x+9 = 24x+2

4. Solve! (picture attached)
I hope this helped! feel free to comment if you need any clarification, though!

Answer:

12 years

Step-by-step explanation:

A = 9 ft = 108 inch

B = 2 ft = 24 inch

So, (108 - 24) = 84 inch

A 9 ft - B 2 ft = 7 ft distance

84 inch ÷ 7 feet = 12 it will take 12 years

A = 17 inch × 12 years + 108 inch = 312 inch or 26 ft

B = 24 inch × 12 Years + 24 inch = 312 inch or 26 ft

Resolver xfa... El taller trata de division de polinomios o algo asi
luda_lava [24]

La altura del triangulo está dada por el polinomio:

p(x) = a + 4

<h3></h3><h3>¿Cual es la altura del triangulo?</h3>

Recordar que para un triangulo de base B y altura H, el area es

A = B*H/2

En este caso, sabemos que la base es B = (4*a^2 + 6)

Y el area es A = 2a^3 + 8a^2 +3a +12

Entoces la altura será un polinomio tal que:

P(a)*(4*a^2 + 6)/2 = 2a^3 + 8a^2 +3a +12

P(a)*(4*a^2 + 6) = 2*(2a^3 + 8a^2 +3a +12) = 4a^3 + 16a^2 + 6a + 24

Podemos ver que p(a) va a ser un polinomio de grado 1, entonces:

p(a) = (c*a + b)

Reemplazando eso:

(c*a + b)*(4*a^2 + 6) = 4a^3 + 16a^2 + 6a + 24

Expandiendo:

(4c)*a^3 + (6c)*a + (4b)*a^2 + 6*b = 4a^3 + 16a^2 + 6a + 24

Comparando terminos del mismo exponente, podemos ver que:

(4c) = 4

6c = 6

4b = 16

6b = 24

Resolviendo esas ecuaciones para c y b, podemos ver que:

b = 16/4 = 4

c = 4/4 = 1

Entonces la altura del triangulo está dada por el polinomio:

p(x) = a + 4

Need help on question 4??
Anit [1.1K]

HK consists of two part, HJ and JK

HK = HJ + JK

We know that:

HK = 12.2ft

JK = 3.1ft

HJ = ?

Let's plug our values into the equation above.

12.2ft = HJ + 3.1ft

Subtract 3.1ft from both sides.

9.1ft = HJ

Which of the following is not the same as 1.69 meters? 0.0169 km 0.169 dkm 169 cm 1,690 mm
bezimeni [28]

Answer:

0.0169 km.

Step-by-step explanation:

km - kilometers (One kilometer is equal to 1000 meters.)

dkm - dekameters (One dekameter is equal to 10 meters.)

cm - centimeters (One centimeter is equal to 0.01 meters.)

mm - millimeters (One millimeter is equal to 0.1 meters.)

Used a calc to check each of the values to see if they equal 1.69m and km was the one that wasn't equal. Instead it was 16.9.
