La respuesta es 6.92 en su expresión más pequeña porque dice la altura de un triángulo equilátero es igual solo sacas las fórmula de la altura de un triángulo que es a^2=c^2+B^2 osea haci que sustituye con valores h^2= 8^2-4^2=h^2 8x8=64 4x4=16 64-16= √48 = 6.92
Subtract: 11a2– 15b2.
The difference can be displayed as (√11a - √15b) (√11a + √15b).
What are Algebraic Identities?Algebraic identities are equations in which the right-hand side of the equation's value is exactly equal to the left-hand side of the equation's value. Any value for the variables satisfies them. To further comprehend this, let's look at an illustration.
(a + b)² = a² + 2ab + b²(a - b)² = a² - 2ab + b²(a + b)(a - b) = a² - b²(x + a)(x + b) = x² + x(a + b) + abgiven:
11a²– 15b²
Using the identity
(a² - b²)= ( a+ b)(a- b)
so, 11a²– 15b²
[(√11a)²– (√15b)²]
= (√11a - √15b) (√11a + √15b)
Hence, the difference can be displayed as (√11a - √15b) (√11a + √15b).

4. Tikili wants to invest $3500 at her local bank. She will receive an interest rate of 5% compounded
annually. What is the value of her investment after two years?
Answer:
[tex]3863.35 = 3500(1 + \frac{0.05}{2} )^{(2 \times 2)} [/tex]
Step-by-step explanation:
The formula for this equation is
[tex]a = p(1 + \frac{r}{n} )^{(n \times t)} [/tex]
a is the final result
p is the starting amount (deposited)
r is the interest rate
n is the number of times it's compounded
t is the time
because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117
Please double check me I may be wrong, this is my second time doing these type of questions

How would we know the gcf of 4xy+8x^2y-24x^4y^5
9514 1404 393
Answer:
4xy
Step-by-step explanation:
List the prime factors of each term.
4xy = 2·2·x·y8x^2y = 2·2·2·x·x·y24x^4y^5 = 2·2·2·3·x·x·x·x·y·y·y·y·yIdentify a factor that appears in each list. Cross it off of each list and add it to your list of "output" factors. Repeat until you run out of factors that appear in all of the lists.
You should quickly determine that all of the factors of 4xy appear in both other lists. That is the GCF. When you have exhausted the factors of 4xy, there are no more possible common factors.
GCF = 4xy
Then the expression can be factored as ...
= 4xy·(1 +2x -6x^3y^4)
_____
Additional comment
If you use exponents to simplify writing repeated multiplication, you will find that the GCF has the factors with the lowest exponent. Here, the lowest power of 2 is 2^2 in 4xy; the lowest exponents of x and y are 1, also in that term.

To solve this equation, use PEMDAS:
P - Parentheses
E - Exponents
M/D - Multiplication/Division
A/S - Addition/Subtraction
PEMDAS is the method that is used for the order of operations. Multiplication and division are interchangeable, so when there are only those signs left, you solve from left to right. This also applies to addition and subtraction.
Equations must always be solved in the order of PEMDAS -- P, then E, then M/D, then A/S.
Now, to solve the equation:
100 - 2(12 + 13) First, solve what is in the parentheses (P).
100 - 2(25) Next, multiply 2 × 25 (M).
100 - 50 Finally, subtract 50 from 100 (S)
50
100 - 2(12 + 13) = 50

Anthony borrows $6.50 from a friend to pay for a sandwich and drink at lunch,
Then he borrows $3.75 from his sister to pay a library fine,
Choose an equation to express Anthony's total debt that day.
What is the answer. If it's correct I will give a heart, many points, 5 review stars, and brainliest ok.
Answer:
C: -$6.50 + (-$3.75) = -$10.75
Step-by-step explanation:
Anthony owes his friend $6.50, so he has -$6.50
Anthony owes his sister $3.75, so he has -$3.75
Add up the debt to figure out how much debt he has!
-$6.50 + (-$3.75) = -$10.75
however, because this is asking about total debt, it is NOT C.
the total debt (-) is $10.75, which is represented in answer D. this means he owes $10.75if you choose C, the total debt (-) for -$10.75 would actually be positive. think about it like if you have a negative negative, you get a positive, so C would actually be credit.comment or message me if you have any questions :)

Lightning travels much faster than thunder, so lightning is seen before thunder is heard. Using inductive reasoning and the graph to the right, if you count 60 s between the lightning and thunder, how far away is the storm?
Answer:
The correct answer is 9 seconds.
Step-by-step explanation:
On your graph, use a ruler and your eye to get the best fitting line.
Then find the time in seconds (45) which is between 40 and 50 on the x-axis.
Go across to the y axis. You will find it is about 9 seconds.

-2 (5x-4)= 8-3x solve for x
Answer:
x=0
Step-by-step explanation:
-2*(5x-4)=8-3x
-2x * 5x -2 * -4= 8 -3x
-10x+8=8-3x
-10x+3x+8=8-3x+3x
-10x+3x+8=8-3x+3x
-7x+8=8-3x+3x+8
-7x+8=8
-7x=8-8
-7x=0
x=0
Answer:
x = 0
Step-by-step explanation:
First, distribute
- 2 (5x - 4) = 8 - 3x
-10x + 8 = 8 - 3x
Next, rearrange the terms
-10x + 8 = 8 - 3x
-10x + 8 = -3x + 8
Then, Subtract 8 from both sides of the equation
-10x + 8 = -3x + 8
-10x + 8 - 8 = -3x + 8 -8
Then, simplify (I'm not gonna show how but if you want me to just let me know)
-10x = -3x
Then, add 3x to both sides of the equation
-10x = -3x
-10x + -3x = -3x + 3x
Then, simplify
-7x = 0
Then, divide both sides of the equation by the same term
-7x = 0
-7x/-7 = 0/-7
Finally, simplify
x = 0/-7
and you'll get
x = 0
