Answer:
[tex]x^2-15x+56[/tex]
Step-by-step explanation:
Use the FOIL distributive method: [tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
---------------------------------------------------------------------------------------------
Thus, [tex]\left(x-7\right)\left(x-8\right)=x\times x +x\left(-8\right)+\left(-7\right)x+\left(-7\right)\left(-8\right)[/tex]
Multiply them to get:
[tex]x^2-8x-7x+56[/tex]
[tex]x^2-15x+56[/tex]

Junior is saving money in his piggy bank. He starts with and adds two pennies each day. Create an table and a graph for the function for which represents the number of days since Junior started saving money and y represents the total money he has saved
The required expression for the Junior started saving money and y represents the total money he has saved is y =2x.
Given that,
Junior is saving money in his piggy bank. He starts with and adds two pennies each day.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Let the number of days, junior saved money be x and the total amount of money he saved be y.
He starts with and adds two pennies each day. which implies,
On day 1 he saved 2 pennies, the next day i.e. day 2 is saved 4 pence and so on and on day x he saved a total of 2x pennies in his piggy bank. Results,
y = 2x
Thus, the required expression for the Junior started saving money and y represents the total money he has saved is y =2x.

I'm sorry if this is incorrect, but I think the answer is [tex]-2, \sqrt{5}, 4, 3^2[/tex]
Explanation: A negative number will always be the least. 3 squared is actually 3*3 and that would be 9. The square root of 5 is 2.2360679775 which is less than 4 so that would go in the second place. I hope this makes sense! :)

A circle has a radius of 7 inches. What is the area of the circle? Use 3.14 for p.
(Area of a circle = pr2)
Answer:
The answer is
153.86 sq. inchesStep-by-step explanation:
Area of a circle is given by
A = πr²where r is the radius of the circle
From the question
r = 7 inches
So the area of the circle is
A = 3.14(7)²
= 3.14 × 49
We have the final answer as
153.86 sq. inchesHope this helps you
Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14
We know,
Area of the circle = πr²Here,
π = pi (An irrational number used for curves)r = radius of the circleSo, let's find the area,
➝ Area of the circle = πr²
➝ Area of the circle = 3.14 × 7²
➝ Area of the circle = 3.14 × 49
➝ Area of the circle = 153.86 inch²
Hence, Area of the circle:
[tex] \huge{ \boxed{ \bf{153.86 \: {inch}^{2} }}}[/tex]
And we are done !!

In Argentina, a cow on a ranch is expected to need an average of 4200 m2
of grassland for food.
What size does a ranch need to be to feed 4500 cows?
Give your answer in hectares.
The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:
[tex]1 \: cow = 4200 \: {m}^{2} [/tex]
Then, for 4500 cows:
[tex]4500 \: cows = 4200 \: {m}^{2} \times 4500[/tex]
[tex]4500 \: cows = 18900000 \: m {}^{2} [/tex]
We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:
[tex]1 \: hectare = 10000 \: {m}^{2} [/tex]
[tex]x \: hectare = 18900000 \: {m}^{2} [/tex]
Then, putting them in proportion, We will get:
[tex]x = \dfrac{18900000}{10000} hectares[/tex]
[tex]x = \boxed{ 1890 \: hectares}[/tex]
So, the total area in hectares = 1890 hectares.
And we are done !!

Since we know sin^2 θ = (sin θ)^2
In our problem,
sinθ = 2/sqrt(3)
Let's plug this value into our expression above.
(2/sqrt(3))^2
Let's square both terms individually.
2^2 = 4
(sqrt(3))^2 = 3
The final answer = 4/3
what will be number of zeros in the square of the number 100? pls answer fasttttttttttt
Answer:
4
Step-by-step explanation:
The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000
Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.
So, the number 10,000 which is the square of 100 has 4 zeros.
Hope this helped!

Answer:
Option (1)
Step-by-step explanation:
Planes ZWV (shaded side) and plane TUV (Top of the box) are the two sides of the given cube or box in the picture attached,
Common edge of the given planes is side SV.
Common edge or the line where two planes meet is the line of intersection of two planes.
Therefore, line SV will be the line of intersection of the given planes.
