Answer:
B
Step-by-step explanation:
For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.
You can go through each answer choice and determine whether or not it would work:
A. 12, 5, and 7
5 + 7 > 12 --> 12 > 12 (NOT true)
B. 10, 15, and 24
10 + 15 > 24 --> 25 > 24 (true!)
C. 9, 22, 11
11 + 9 > 22 --> 20 > 22 (NOT true)
D. 21, 7, and 6
7 + 6 > 21 --> 13 > 21 (NOT true)
This means that the correct answer is B.

Solve each system using ELIMINATION. Remember to check!
4) 4x + y = 8 5) 3x + 5y = 54
–3x – y = 0 6x + 4y = 72
Answer:
Step-by-step explanation:
Elimitation:
4) add both.
x=8. y=-24
5) multiply 2.
6x+10y=108.
subtract.
6y=36.
y=6.
x=8.
check:
4(8)-24=8. Correct.
-3(8)-24=0. correct.
3(8)+5(6)=54. Correct.
6(8)+4(6)=72 correct.
Hey there!
Given the following system:
4x + y = 8
-3x - y = 0
We do not need to change the equations at all, because the "y"s will already cancel eachother out. When we add the equations together, we get
x = 8
Now, we have to solve for y: We can do so by plugging in the value of x in to one of the equations:
4(8) + y = 8
Now we solve:
4(8) + y = 8
32 + y = 8
y = -24
The solution to the first given system is (8, -24)
Now, we can check by plugging the numbers into both equations, and seeing if they are true:
4(8) + (-24) = 8
32 + (-24) = 8
8 = 8 ~ TRUE
Now, we check the second equation:
-3(8) - (-24) = 0
-24 - (-24) = 0
-24 + 24 = 0
0 = 0 ~ TRUE
Both equations are true, which means that the correct solution to the first given system is (8, -24)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For the second given system, we are going to have to change one of the equations because, when added, the "x" or "y" values will not cancel out.
3x + 5y = 54
6x + 4y = 72
We can divide the second equation by -2 so the "x" values will cancel out:
-3x - 2y = -36
Now, we add the equations:
3y = 18
And solve for "y":
3y = 18
y = 6
Now, we plug the "y" value into one of the equations and solve for "x":
3x + 5(6) = 54
3x + 30 = 54
3x = 24
x = 8
The solution to the second given system is (8, 6)
Now, we can check by plugging the "x" and "y" values into both equations:
3(8) + 5(6) = 54
24 + 36 = 54
54 = 54 ~ TRUE
Now, we check the second equation:
6(8) + 4(6) = 72
48 + 24 = 72
72 = 72 ~ TRUE
Both equations are true, which means that the correct solution to the second given system is (8, 6)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Step-by-step explanation:
Leah plans to purchase merchandise from a department store that is valued at $100. She will use $20 in-store bucks that she has earned
plus a 30% discount coupon to reduce her final cost. What is the final cost of the items (before tax) if the $20 store bucks are applied before
the 30% discount?
The final cost of the items (before tax) if the $20 store bucks are applied before the 30% discount is $76.
The discount of 30% will be applied on $80 ($100 - $20), resulting to a discount of of $24 ($80 * 30%).
This discount is subtracted from the total value of the merchandise to get the final cost as $76 ($100 - $24).
Thus, the final cost to Leah to purchase the merchandise from the department store is $76.

Using the remainder theorem see if (x-2) and (x+5) are factors of the polynomial
X^2+3x-10
Answer:
See explanations below
Step-by-step explanation:
Given the polynomial function
P(x) = X^2+3x-10
To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0
For x-2
x - 2 = 0
x =2
P(2) = 2²+3(2)-10
P(2) = 4+6 -10
P(2) = 10-10
P(2) = 0
Since the remainder is zero, hence x-2 is a factor of the polynomial
Similarly for x+5;
x+5 = 0
x = -5
P(-5) = (-5)²+3(-5)-10
P(-5) = 25-15-10
P(-5) = 10-10
P(-5) = 0
This also shows that x+5 is a factor

Gideon is filling a container with sand. How much sand will fit in the container
Answer:
418cm³
Step-by-step explanation:
volume of cuboid=l×b×h=11×2×19=418c³
Answer:
418 square centimeters.
Step-by-step explanation:
Since the formula for volume is length times width times height, you would have to multiply 11 (length) times 2 (width) first, and you would get 22. Next, you have to multiply 22 with the height (19). After you do this you will get your final answer which is 418 square centimeters.

For P(x) = 2x^4 – 5x^3+x-10, use synthetic substitution to evaluate P(-2). P(1), and P(2).
Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20

[tex]\angle 4 = 101[/tex]
Step-by-step explanation:
Given
The attachment
Require
Solve for [tex]\angle 1, \angle 2, \angle 3, \angle 4[/tex]
We start by solving for [tex]\angle 1[/tex]
[tex]\angle 1 + 79 = 180[/tex] ---- Angle on a straight line
[tex]\angle 1 + 79-79 = 180 - 79[/tex] --- Subtract 79 from both sides
[tex]\angle 1 = 101[/tex]
[tex]\angle 1 = \angle 2 = \angle 3[/tex] --- Corresponding angles;
So, we have:
[tex]\angle 2 = 101[/tex]
[tex]\angle 3 = 101[/tex]
[tex]\angle 1 = \angle 4[/tex] --- vertically opposite angles
So, we have:
[tex]\angle 4 = 101[/tex]

Ann had 48 fliers to post around town. Last week, she posted 2/3 of them. This week, she posted 3/8 of the remaining fliers. How many fliers has she still not posted?
Answer:
Ann had 48 fliers to post around town
Last week, she posted 2/3 of them
[tex]48 \times \frac{2}{3} = 32 \\ [/tex]
Therefore, she should posted 32 fliers
This week, she posted 3/8 of the remaining fliers
[tex]48 \times \frac{3}{8} = 18 \\ [/tex]
Therefore, she should posted 18 fliers
Total fliers she should post are (32+18)=50 fliers
She still did not post (50-48)= 2 fliers
2 fliers is the right answer.Alyssa sold half of her comic books and then bought 7 more. She now has
