15. Ethan planted sunflowers in different types of soil and measured their growth each week.
Plant 1 started at a height of 10 inches and grew 10 inches per week. Plant 2 started at a
height of 18 inches and grew 8 inches per week. Ethan wants to predict the number of weeks
it will take for the plants to reach the same height.
Ethan concludes that the plants will reach the same height after 50 weeks. Is Ethan correct?
Explain why or why not.
Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer: No he is not correct
Step-by-step explanation:
plant 1 will be taller than plant 2 at 50 weeks
do 50 times 10 = 500in
do 50 times 8 = 400in

Complete the table (100 points)
Answer:
see image
Step-by-step explanation:
You are multiplying x² - 4x + 4 and 6x + 3.
This is set up like:
6x + 3(x² - 4x + 4)
To solve this, we want to multiply each term that is outside of the parentheses with each term that is inside of the parentheses.
Let's start with 6x.
6x • x² = 6x³
6x • -4x = -24x²
6x • 4 = 24x
These numbers will be in the first blank row.
Now, let's move onto 3.
3 • x² = 3x²
3 • -4x = -12x
3 • 4 = 12
These numbers will be in the second blank row.
Now let's write all these numbers together.
6x³ - 24x² + 24x + 3x² - 12x + 12
Combine like terms, pay attention to the exponent.
6x³ - 21x² + 12x + 12
Refer to the completed table below.

What is the area of the rectangle with the given dimensions? *
The dimensions of a rectangle are 2x - 5 and
3x + 3. Which expression represents the area
of the rectangle in simplest terms?
F 6x2 - 9x - 15
G 6x2 - 9x + 15
H 6x + 9x - 15
J 6x - 15x - 9
Given:
The dimensions of a rectangle are [tex]2x-5[/tex] and [tex]3x+3[/tex].
To find:
The expression that represents the area of the rectangle in simplest terms.
Solution:
Area of a rectangle is:
[tex]Area=Length\times Width[/tex]
The dimensions of a rectangle are [tex]2x-5[/tex] and [tex]3x+3[/tex]. So, the area of the given rectangle is:
[tex]Area=(2x-5)\times (3x+3)[/tex]
[tex]Area=2x(3x)+2x(3)-5(3x)-5(3)[/tex]
[tex]Area=6x^2+6x-15x-15[/tex]
[tex]Area=6x^2-9x-15[/tex]
Therefore, the correct option is F, i.e., [tex]6x^2-9x-15[/tex].

What is the Sector area with radius 6 and an angle of 50°? Use 3.14 for pi.
Answer:
15.7 units²
Step-by-step explanation:
The sector area is 50/360 times the area of the circle (since the central area of a complete circle is 360° and that for the sector is 50°), or
Sector area = (50/360)(3.14)(6 units)² = 15.7 units²
If −x+8y=−3 is a true equation, what would be the value of 2(−x+8y)?

A box contains 3 pens, 2 markers, and 1 highlighter. Tara selects one item at random and does not return it to the box. She then selects a second item at random. What is the probability that Tara selects 1 pen and then 1 marker?
Answer:
1/5
Step-by-step explanation:
There are a total of 6 items in the beginning. In the first selection, there is a 3/6 chance that she selects a pen. Since she does not return it to the box, there are 5 items left. The possibility to select a marker is 2/5. Simply multiply the two fractions. You will get 1/5.

What is the GCF for 4x^2yz^3 and 12xz^2
Answer:
The great common factor is:
x(2z)²Steps:
given:
4x²yz³12xz²4x²yz³ = 2²x²z²yz
4x²yz³ = x(2z)²xyz
---------------------------------
12xz² = 4×3xz²
12xz² = 2²3xz²
12xz² = x(2z)²3
The great common factor is: x(2z)²
Answer:
4xz^2.
Step-by-step explanation:
GCF of 4 and 12 is 4
GCF of x^2 and x is x.
GCF of z^3 and z^2 is z^2.
