Need some help with trinomial
Answer:
(x - 6)(x + 2)
Step-by-step explanation:
assuming you require the trinomial to be factorised.
x² - 4x - 12
consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 4)
the factors are - 6 and + 2 , since
- 6 × 2 = - 12 and - 6 + 2 = - 4 , then
x² - 4x - 12 = (x - 6)(x + 2)
x2 + y2 = 100
+

Answer:
Yes, it is...
Step-by-step explanation:
x^2 + y^2 = 100

Answer:
72
Step-by-step explanation:
First. I counted the triangles. Then, I found the area of one triangle. Since the area of a triangle is (base*height)/2, I found the area of one triangle this way: 6x6=36. 36/2=16. After that, I then multiplied the area of the one triangle by four, since there are four triangles. 16x4=72

This is a cross-sectional view of candy bar ABC. A candy company wants to create a cylindrical container for candy bar ABC so that it is circumscribed about the candy bar. If segment AD = 4 cm, what is the smallest diameter of wrapper that will fit the candy bar?
Triangle ABC in which point E is between points A and B, point D is between points A and C, point F is between points B and C, segments AE and EB are congruent, segments BF and FC are congruent, and angles AED, ABF, and DFC are right angles.
7 cm
8 cm
9 cm
10 cm
The diameter of wrapper is the line that passes through its circumference
The smallest diameter of wrapper that will fit the candy bar is 8 cm.
How to determine the smallest diameter?The diven parameter is:
AD = 4 cm
AD = DC
AC = AD + DC
Substitute AD = DC in AC = AD + DC
So, we have:
AC = AD + AD
AC = 2AD
Substitute 4 for AD
AC = 2 * 4
AC = 8
Hence, the smallest diameter of wrapper that will fit the candy bar is 8 cm.

I got 6 because it shows a semi circle, and half of 12 is 6.
Answer:
30
Step-by-step explanation:
one circle = 12
two circle = 12 × 2 = 24
half circle = 12/2 = 6
so
two circle + half circle = 24 + 6 = 30
What is the area of triangle ABC?
Answer:
200 sq units
Step-by-step explanation:
As you might know, 3 angles of a triangle adds up to 180*. Since you already know the angles are 60* there is one more 60*. So by this you know that all the sides are equal.
As the given states, one side is 20. So following the standard way to get the area of a triangle b*h/2; 20*20 = 400 / 2 = 200 sq units

A clothing store is selling a pair of jeans for $17 and a sweatshirt for $8. Which inequality shows the number of sweatshirts Monique can buy along with one pair of jeans if she has $41 to spend? Assume that there is no sales tax.
Answer:
1 pair of jeans and 3 sweatshirts
Step-by-step explanation:
41-17=24
24/8=3
The inequality shows the number of sweatshirts Monique can buy along with one pair of jeans if she has $41 to spend will be; 17x + 8y ≤ 41
What is inequality?An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.
We are given that clothing store is selling a pair of jeans for $17 and a sweatshirt for $8.
Therefore,
41-17=24
Unit price = 24/8=3
Thus 1 pair of jeans and 3 sweatshirts
The inequality shows the number of sweatshirts Monique can buy along with one pair of jeans becomes as;
17x + 8y ≤ 41

find the median of first 10 prime numbers
What is the area of the shaded region?
A. 16π
B. 8π
C. 4π
D. 2π
Step-by-step explanation:
the area of a full circle (360°) is
pi×r² = pi×5² = pi×25
a 40° segment is then just 40/360 = 1/9 of the full circle.
so,
pi×r²×1/9 = pi×25/9 = pi×2.777777777...
so, either there is a mistake in the problem description, or your teacher wants you to cut off the decimals (after the decimal point), in which case D would be the right answer.
since our radius is 5, that makes r² always 25.
there are no integer factors I can divide 25 by to create any of the 4 solutions of 16 or I or 4 or 2.
and there is no integer factor I can divide 360 by to get 25.
so, something is wrong here regarding the problem description. either the radius or the angle or the solution options are wrong and not fitting to each other.

In a survey of 3,000 people who owned a certain type of car, 1,050 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
35 percent
Step-by-step explanation:
1050 / 3000 as a percent
1050 / 3000 = 105 / 300
Divide both sides by 3:
300 / 3 = 100
105 / 3 = 35
35 / 100 = 35 percent
34%
This is because when you divide 1,050 by 3,000 you get 0.34 then turn that into a percent then there you go

Answer:
1. Find the circumference, then multiply that by 120 turns.
Formula for circumference;
C = 2πr
But, we need to find the radius which is 1/2(half) of the diameter, so,
D/2 = R
D = Diameter
R = Radius
20/2 = 10 is the radius.
Plug in values now:-
C = 2(3.14) x 10
C = 6.28 x 10
C = 62.8 is the circumference, now we multiply this by 120 to get the total amount of centimetres it'll go.
62.8(120)
= 7,536 cm it'll go.
2. Find the circumference, then multiply that by 750 turns/revolutions.
C = 2πr
Find radius,
D/2 = R
50/2 = 25 is the radius.
Plug in values now:-
C = 2(3.14) x 25
C = 6.28 x 25
C = 157 cm it'll go.
3. Same thing, find circumference then compare values.
Given that radius is 10,
Use the formula for circumference;
C = 2πr
Replace values:-
C = 2(3.14) x 10
C = 6.28 x 10
C = 62.8 cm is the circumference of the first circle.
Now the second circle, (use same formula)
C = 2πr
Find radius,
D/2 = R
10/2 = 5 is the radius.
Replace values:-
C = 2(3.14) x 5
C = 6.28 x 5
C = 31.4 cm is the circumference for the second circle.
Now subtract the second circle's circumference from the first:
62.8 - 31.4
= 31.4, 31.4 cm is how much greater the second circle is than the first.
4 - 5. Find circumference, (using circumference formula)
C = 2πr
Find radius,
D/2 = R
760/2 = 380
Replace values:-
C = 2(3.14) x 380
C = 6.28 x 380
C = 2,386.4 km is the distance he'll travel.
If he wants to travel around it with 2,000 km, he'll need to travel at least once.

Moussa owns a small business selling clothing. He knows that in the last week 92 customers paid cash, 5 customers used a debit card, and 25 customers used a credit card.
If next week, he is expecting 1600 customers, about how many would you expect to pay with cash? Round your answer to the nearest whole number.
Answer:
1207
Step-by-step explanation:
Total number of customers last week: 92 + 5 + 25 = 122
Number of customers who paid cash: 92
Percent of customers who paid cash last week: 92/122 × 100% = 75.4%
Next week:
Total number of customers: 1600
Expected number of customers paying cash:
75.4% of 1600 = 0.754 × 1600 = 1207
