Which of the following shows the correct match of the box numbers and the genotype of the offspring?

Use foil to explain how to find the product of (a+b)(a-b). Then describe a shortcut that you could use to get this product without using foil.

Answers

FOIL stands for Front Outter Inner Last

F- multiply the first two terms axa= a^2
O- multiply the two terms on the outside a x -b= -ab
I- multiply the two inner (middle) terms - b x a= ab
L- multiply the last variable in each term= b^2

A shortcut without using FOIL is called the difference of squares and can be rewrote as (a^2-b^2)

Using the FOIL method -
Firsts: a×a= a^2
Outers: a×-b= -ab
Inners: b×a= ab
Lasts: b×-b= -b^2

Combine -
a^2-ab+ab-b^2
= a^2-b^2

This particular pair of binomial brackets with a + and a - in them can be expanded with the difference of two squares:
(a+b)(a-b) = a^2-b^2
This works for binomial brackets with a + and a - in each of them, and where the two terms in each bracket are the sameFor example:
(x+5)(x-5)= x^2-25
So remember,

Percy is plotting points on a graph. The ratio of y-value to x-value is 2 to 3 for each point. What will be the x-value of a point with a y-value of 18?

Answers

It is 27 because if you do 9 times 2 you get 18 so you would do 9 times 3 which is the value of x, which is equal to 26

Answer: Value of x = 27

Explanation:

Percy is plotting a coordinate on the graph.

Now the ratio of y-value to x-value is 2 to 3 for each point.

Suppose Value of is 3a and y value is 2a

So, the coordinate of the point is (3a,2a)

Now we find the x value of the coordinate when value of y is 18.

2a is same as 18

2a = 18

a = [tex] \frac{18}{2} [/tex]

a = 9.

Now find the x ordinate

put the value of a=9 into 3a

3a = 3(9) = 27

So the final answer is :

Value of x = 27 when value of y = 18

(6,0)

The x values are: 1, 2, 3, 4, 5, 6
The y values are: 5, 4, 3, 2, 1, 0
In the same order

As x increases by 1, y decreases by 1
So we have perfect negative linear correlation

Side Note: The equation of the line that goes through all of the points is the equation y = -x+6 which can be written as x+y = 6. This line has a negative slope (slope = -1)

If five bags of mulch covers 32 square feet, how many square feet could 16 bags covers?

Answers

Answer:

102.4 square feet

Step-by-step explanation:

(32/5)*16=102.4

Final answer:

One bag of mulch covers 6.4 square feet. Therefore, 16 bags will cover 102.4 square feet.

Explanation:

To find out how many square feet 16 bags of mulch will cover, we need to first determine the coverage of one bag. If 5 bags cover 32 square feet, then one bag covers 32 ÷ 5, which equals 6.4 square feet. Multiplying the area covered by one bag by 16 bags gives us a total coverage, of 6.4 × 16, which equals 102.4 square feet. Therefore, 16 bags of mulch will cover 102.4 square feet.
