What is the value of k?
Answer:
[tex]( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12[/tex]
Answer:
Step-by-step explanation:
a² + 2ab + b² = (a + b)²
2ab = 2 * x * 8 = 16x
x² + 16x + 64 = x² + 2* x * 8 + 8²
= (x + 8)²
x² + 16x + 8 - (x +8)(x - 4) = (x+8)² - (x+ 8) (x -4)
= (x +8)(x +8) - (x + 8)(x - 4)
(x +8 ) is common in both terms
= (x + 8) [ (x + 8) - (x - 4) ]
= (x + 8) [ x + 8 - x + 4 ]
{Combine like terms. so x + (-x ) = 0 and 8 +4 = 12}
= (x + 8) [ 12]
k = 12

Help me please I’ll give brainlest
Answer:
-17
Step-by-step explanation:
1) rewrite: (3 - n) divided by 2 = 10
2) Multiply both sides: (3-n)/ 2 = 10
3) move constant to the right: 3 - n = 20
4) calculate: -n = 20 - 3 then, -n = 17
5) change signs: n = -17

the mean would increase.
the mean would decrease.
the median would increase.
the median would decrease.
Answer:
1. Mean: 103
2. Median: 8
3. Mean would increase.
Step-by-step explanation:
1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1,236
Then, 1,236/ 12 = 103
Therefore, our answer!
2. Put the numbers in order from least to greatest:
1, 6, 7, 8, 9, 11, 16
Cross out one on each side until you get to the middle.
3. Add up all original numbers to get a mean of: 2.7 and then add up all the numbers including six to get a mean of: 3.2 As you can see, the mean increased.

The Mean is 103 ,Median is 8 and Mean would increase
What is mean and median?
The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number.
according to the question,
1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1236
Then, 1236/ 12 = 103
Therefore, our answer
2. Put the numbers in order from least to greatest:
1, 6, 7, 8, 9, 11, 16
Cross out one on each side until you get to the middle.
Median is 8

for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²

Which of the following equations is an example of the Associative Property of Addition?
Answer: Choice B
(3+4) + 2 = 3 + (4+2)
=========================================
Explanation:
The general rule for the associative property of addition is
(a+b)+c = a+(b+c)
the a,b,c stay in the same order from left to right. The only thing that changes is the way we group the pair of terms. On the left side, we have a & b together with c left out. Then on the right side, we have b & c together with 'a' excluded.
Addition of any group of numbers can be done in any order, which is why this property is valid (though perhaps there's a more rigorous proof out there). For this specific problem, a = 3, b = 4, and c = 2.
Answer: I think the answer to your question is option B.

The sum of two numbers is 80. If the difference between the same two numbers is 8, find the two numbers.
Answer:
The numbers are 44 and 36
Step-by-step explanation:
n + n - 8 = 80
2n - 8 = 80
2n (- 8 + 8) = 80 + 8
2n = 88
2n/2 = 88/2
n = 44
44 - 8 = 36
