Factor completely 121x2 − 16. (11x − 4)(11x + 4) (11x − 4)(11x − 4) (4x − 11)(4x − 11) (4x − 11)(4x + 11)
Answer:
(11x+4)(11x-4)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=11x and b=4.
Answer:
(4x − 11)(4x + 11)

Answer: DE is 15 and AB is 6
Step-by-step explanation:
Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).
Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.
So, to find DE, just multiply the corresponding side, BC, by 300%.
5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?
For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.
find the total cost of a video game that costs 29.99 with 8% tax
Answer:
32.39
Step-by-step explanation:
29.99 is 100%
? is 8%
?= 29.99*8/100 about 2.40
so the final cost is the price + tax = 29.99 +2.40= 32.39
3( 2x+7) = 6(x +4) -3
is this problem no solution, infinite solution, or one solution
Answer:
3(2x + 7) = 6(x +4) - 3
<=> 6x + 21 = 6x + 24 - 3
<=> 21 = 21
=> this problem is infinite solution
Step-by-step explanation:
While Jackie was in Hawaii, she would dive for shells. One afternoon she dove −7.8 feet. Her next two dives were each 2 1/8 feet deeper than the dive before it. What were the depths of her second and third dives?
Given :
One afternoon she dove -7.8 feet.
Her next two dives were each 2 1/8 feet deeper than the dive before it.
To Find :
The depths of her second and third dives.
Solution :
Depth of her second dive,
[tex]d_2=-(7.8+2\dfrac{1}{8})\\\\d_2=-(7.8 + \dfrac{17}{8})\\\\d_2 = -9.925\ feet[/tex]
Depth of her third dive,
[tex]d_3 = -(7.8 + 2\times 2\dfrac{1}{8})\\\\d_3 = 12.05\ feet[/tex]
Therefore, the depths of her second and third dives is -9.925 feet and -12.05 feet.
Hence, this is the required solution.
Please help, i can't figure this out and im ready to pull my hair out!!!
Answer:
I'm sorry I don't know the equation, but she walks 3 mph.
Step-by-step explanation:
We know that the answer is asking for speed, which needs both distance and time, so we also need both. Which is where the 9 mph is used. 9 mph means its a difference. b means biking mph, w means walking mph, sooo ----->>> b=w+9, and the difference in the 1st equation is 36, which means the first equation is 4 times larger than the b=w+9, so she walked 48 miles, as well as walked 12 miles in 4 hours. Divide then distances by 4, and you get 12 miles and 3 miles in one hour. Or 12 mph & 3 mph, which fits into 12=3+9. So she walks 3 miles per hour.

Select all equations that can result from adding these two equations or subtracting one from the other.
x+y=12
3x-5y=4 PLZ
HELP QUICK I WILL GIVE BRAINLYIEST
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

The meal costs $52.95 for 5 people. Jenna ordered a dessert for $2.50. If Jenna deducts this amount from the total, how much will each of the other people pay for their meal?
Answer: $12.61
Step-by-step explanation:
Given : Total cost of meal for 5 people = $52.95
Jenna ordered a dessert for $2.50.
Total cost other 4 need to pay = $ (52.95- 2.50) = $ 50.45
Now , each person will pay [tex]=\$\dfrac{50.45}{4}\approx \$12.61[/tex]
Hence, each of the other person need to pay $12.61 .

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 3 in. What are actual dimensions of the kitchen
Answer:
5feet by 4/3feet
Step-by-step explanation:
The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 /3 in. What are actual dimensions of the kitchen.
From the question, we were given the conversation rate of 1/4 in = 1/2 ft In the model,
To get actual dimensions of the kitchen if the kitchen measures 2 1/2 by 2 3 in. Then
✓Let us convert 2 1/2in to feet first= 5/2in as improper fraction.
If 1/4 in = 1/2 ft
5/2in = x ft
Then cross multiply, we have
(5/2×1/2)= 1/4 × X
5/4 = 1/4X
Make X subject of the formula
X= (5/4)/(1/4)
X=5ft.
✓Let us convert 2/3in to feet
If 1/4 in = 1/2 ft
2/3in = x ft
Then cross multiply, we have
1/4×X=2/3×1/2
X=(2/3×1/2)/(1/4)
X=4/3feet
Therefore, the actual dimensions of the kitchen is 5feet by 4/3feet

You have one box that is 2 3 11 feet tall and a second box that is 2.27 feet tall. Write the decimal expansion for 2 3 11. If you stack the boxes, about how tall will the stack be?
Answer:
The stack will be 4.54 feet tall
Step-by-step explanation:
Firstly, we want to write the decimal expression for 2 3/11
That will be 2 + 0.2727
To 2 decimal place, that will be 2.27
Staking the two boxes means we are placing one on the other
So the height of the stack will be 2.27 + 2.27 = 4.54 feet
Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because 60 - 5 = 12. Complete the
statement about whether Noah's method always works.
His method never
works because multiplying by does not give the same result as dividing by 5.
Answer:
he is correct because 20% is the same thing as 1/5 amd 1/5 is the same thing as dividing by 5
