Answer: (a + 2)(a - 2) which is the first answer choice
=========================================================
Explanation:
Use the difference of squares factoring rule which is x^2 - y^2 = (x+y)(x-y)
In this case, x = a and y = 2
x^2 - y^2 = (x+y)(x-y)
a^2 - 2^2 = (a+2)(a-2)
a^2 - 4 = (a+2)(a-2)

"Is the product of 3/6 × 5/4 equal to the product of 3/4 × 5/6?"
If we can turn 3/6 * 5/4 into 3/4 * 5/6 using only legal math steps, then the answer is yes.
3/6 * 5/4 =
Breakup each fraction into a product of fractions.
= 3/1 * 1/6 * 5/1 * 1/4
Use the associative and commutative properties of multiplication to change the order and grouping of the multiplication.
= (3/1 * 1/4) * (5/1 * 1/6)
Do each product in parentheses.
= 3/4 * 5/6
This shows that 3/6 * 5/4 = 3/4 * 5/6

Answers
Answer:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
Step-by-step explanation:
The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:
Between
83 - 6.5 = 76.5
83 + 6.5 = 89.5
So:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
3. The sum of two numbers is 30 and their difference is 12. Find the two numbers.
Answers
Answer:
I don't know is it 12 and 16 I'm not sure
Answer:
The two numbers are 21 and 9
Step-by-step explanation:
Let the two numbers be a and b
The sum of these numbers is 30
a+b=30
The difference between these numbers is 12
a−b=12
―――――――――
I. You can solve this by logic.
If the two numbers were exactly equal, then they would both be 15.
15+15=30
But the difference would be 0, not 12
So if you lowered b by one point, and added that to a, then the two numbers would be 16 and 14, and the difference would be 2.
So you can see that for every point you subtract from b to add to a, you increase the distance between them by 2
So, by logic, you need to subtract 6 points from b and add them to a to create a difference of 12
(15+6) minus (15−6) gives a difference of 12
.m21.....−mm∩9 = 12
Answer:
The two numbers are 21 and 9
―――――――――
II. You can solve this by math
These are simultaneous equations, so you can solve them by math.
.a+b=30
.a−b=12

2a +0=42

Identify which system of equations represents the situation.
Answers
Answer:
4w + 3c = $27
5w + c = $25.50
Step-by-step explanation:
Let us assume the w represent the cost of the sandwich
And, the c represent the cost of the bowl in a soup
Now the equations are
4w + 3c = $27
5w + c = $25.50
These two should be the equations that represent the situation

Width 2in

length 4in
Step-by-step explanation:
If he want the length to be four he has to take 2 sqares off at the end to be left with his height as 3 so vertical from top to bottom and width (the two sqaures at the end of the photo to the left) would be 2. :)
Width of box=2in
Height of box=3in
Length of box=6in
Volume=2(3)(6)=36in³Now
length of the box is 4in
Product of width and height=36/4=9in²
They must be of 3×3 in or 4.5×2 in
