Trying to factor by splitting the middle term
4.1 Factoring x2+11x-9
The first term is, x2 its coefficient is 1 .
The middle term is, +11x its coefficient is 11 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 1 • -9 = -9
Step-2 : Find two factors of -9 whose sum equals the coefficient of the middle term, which is 11 .
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

15
Step-by-step explanation:
I divided 150 by 10 and got a solution of 15.
Find the area for the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.
Answer: 1661.9 yards
Step-by-step explanation:
The formula for the are of a circle is [tex]\pi r^{2}[/tex], so you would do multiply [tex]23^{2}[/tex] (which equals 529) by [tex]\pi[/tex] which gets you 1661.9.
Help please. Seriously. I've posted this question 2 times. I seriously need help on this, guys.
Answer:
20s=m
Step-by-step explanation:
I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)
Answer:
s= students m= money ($20) equation_ s*m= total
Step-by-step explanation:
I'm not entirely sure on specifics, such as how man students. so, I can't pinpoint an exact total. I hope this helps though

A prism is completely filled with 1120 cubes that have edge lengths of 12 in.
What is the volume of the prism?
Answer: if 1/2in then 140 if 12in then 1,935,360
Step-by-step explanation: It's v=a^3, a being the length of a side. Since we know the length...
V=12^3, which equals 1728. So each cube has a volume of 1728 inches. Now, multiply that by 1120. You get...
1,935,360!
Answer : 1120 x 12 = 13440

The largest living thing on earth is a California sequoia tree named the “General Sherman”. The diameter of the tree at the base is 36 feet. What is the approximate circumference of the trunk?
216 feet
12 feet
54 feet
108 feet
Answer:
36x2 gives us the answer which is 54 feet
Step-by-step explanation:
The solution is, the approximate circumference of the trunk is 113 ft.
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
here, we have,
given that,
The largest living thing on earth is a California sequoia tree named the “General Sherman”. The diameter of the tree at the base is 36 feet.
now, we have to find the approximate circumference of the trunk .
we have,
The diameter of the tree at the base is 36 feet.
so, radius = 36/2 = 18 ft
we know that,
circumference of the trunk = 2πr
here, r = 18
so, we get,
circumference of the trunk is:
=2 * 3.14 * 18
=113 ft
Hence, the approximate circumference of the trunk is 113 ft.

Kelly walks 1/5 mile to school every day. Jamie walks 1/2 as far as Kelly. How does Jamie walk to school every day?
Answer:1/10 a mile
Step-by-step explanation:
Answer:
Jamie walks 528 feet to school.
Explanation:
Kelly walk 1/5 of a mile, so she walks about 1056 feet to school every day.
Jamie walk 1/2 of that. So 1056÷2 = 528.
what is the value of t?
Answer:
Hello! answer: t = 50

The set designers of a school play need to determine the cost of the gold paper they’ll need to create stars in the shape of the shaded region in the figure below.
The gold paper is being sold at Michaels for $2.45 per square centimeter.
The set designers have a $6,000 budget to make these stars. Do they have enough money to make 50 stars?
Answer: Yes, they do.
Step-by-step explanation: You have to calculate the area of the star; you do this by calculating the area of the square and subtracting the area of the unshaded parts, which is a quarter of a circle.
Therefore,
15^2 - pi * 7.5^2 = 48.28541324 cm squared
Multiply this answer by $2.45 for one star:
Equals $118.2992624
Multiply by 50,
Equals $5,914.96
Since this is less than $6,000 they have enough money to make 50 stars

Key information - 180° - 82° = 98° (missing angle)
Equation - [tex](5y+12)=98[/tex] [tex]y=17.2[/tex]
Step-by-step explanation:
Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.
then use the statement to solve for y and make it equal to 98°
[tex](5y+12)=98[/tex]
[tex](5y-12)[/tex] = -12 subtract 12 from both sides
[tex](5y)[/tex] = 86 Now solve for y by dividing 86 ÷ 5
y = 17.2
