(x+y)(x-y) if x=-3 and y=-5
Answers
Answer:
-16
Step-by-step explanation:
As we have
\( {x}^{2} - {y}^{2} = (x + y)(x - y)\)
Here
x= -3
y= -5
Subtitute x and y
\( {x}^{2} - {y}^{2} \\ ( - 3{)}^{2} - ( - 5 {)}^{2} \\ 9 - 25 \\ - 16\)
Answer:
-16
Step-by-step explanation:
We first need to substitute
Since x = -3 and y = -5
(-3+-5)(-3 - -5)
Let's Solve (-3+-5)
which = -8
Then Solve (-3 - -5)
which = 2
Now -8 × 2 = -16
Hence, Answer = -16

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

How to use a pattern to find the product of a decimal
Answers
Answer:
A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.
Answer:
Step-by-step explanation:
So I don't know if this will help or is the answer that you're looking for but here:
If you're multiplying a decimal by 1, it obviously stays the same.
ex: 1 x 0.25 = 0.25
If you multiply by 10 then you move the decimal place once to the right, as it gets bigger
ex: 10 x 0.25 = 2.5
you can do this for any number:
10 x 3.44 = 34.4
you can also use any power of 10.
10^2/100
100 x 2.75 = 275/275.0

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

Explanation: The degrees of those angles are congruent because they are corresponding angles. This means we can use 4x-14=x+85 to find x.
4x-14=x+85, subtract x on both sides.
3x-14=85, add 14 on both sides.
3x=99, divide 3 on both sides.
x=33

Rosena bought an 8 pack of donuts to share with her friend at school. The donuts cost $28.00 all together. What is the unit rate for the donuts in $/donuts?
Answers
Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because \(8\div 8=1\).
The price of the 8-pack of donuts was \(\$28.00\). Diving by 8, we have:
\(\frac{\$28.00}{8}=\boxed{\$3.50}\)
Therefore, the unit rate for the donuts is $3.50/donut.
Answer:
$3.5
28/8 = 3.5
