(2x + 7)(x - 5)
Answer:
[tex]2x^{2}[/tex]- 3x - 35
Step-by-step explanation:
(2x + 7)(x - 5) = [tex]2x^{2}[/tex] - 10x + 7x - 35 = [tex]2x^{2}[/tex]- 3x - 35
To expand multiply each tern in one set of parenthesis by each term in the other set:
(2x+7) (x-5)
Set up each multiplication:
2x*x + 2x*-5 + 7*x + 7*-5
Simplify:
2x^2 -10x +7x -35
Combine like terms:
2x^2-3x-35
Is AABC-ADEF? If so, identify the similarity postulate or theorem that applies 30- A
Answer:
C. Similar - AA
Step-by-step explanation:
From the diagram given, we know that all 3 angles of ∆ABC are congruent to all corresponding 3 angles of ∆DEF.
If we know just two of the angles of the two triangles given are equal to each other, it is enough information for us to prove that they are similar to each other based on the AA Similarity theorem.
The corresponding three angels of both triangles are equal, therefore, based on AA, they are similar to each other.
Security A rounds every 2 minutes and 20 seconds in the gate 1. Security B
rounds every 1 minute and 40 seconds in the gate 2. If they conduct rounds at
the same time After how many minutes they will rounds together again?
Answer:
They will do rounds together again in 11 minutes and 40 seconds.
Step-by-step explanation:
Security A rounds every 2 minutes and 20 seconds in the gate 1.
That is, after 2*60 + 20 = 120 + 20 = 140 seconds.
Security B rounds every 1 minute and 40 seconds in the gate 2.
That is, after 1*60 + 40 = 60 + 40 = 100 seconds.
After how many minutes they will rounds together again?
First, we find this is seconds, which is the least common multiple between 140 and 100. Factoring them by prime factors:
140 - 100|2
70 - 50|2
35 - 25|5
7 - 5|5
7 - 1|7
1 - 1
lcm(140,100) = 2*2*5*5*7 = 700 seconds
They will do rounds together again in 700 seconds, which is 11 minutes and 40 seconds.

Write the expression using exponents.
2.1•x•z•z•z•z
Answer:
I believe it's 2.1xz^4
Step-by-step explanation:
The expression of exponent is 2.1.x.z⁴ or 2.x.z⁴.
What is exponent?The process of expressing large numbers in terms of powers is what is meant by the term "exponent." Therefore, the term "exponent" refers to the number of times a number multiplies itself.
The exponent is represented by the character (^), which is also known as a carrot.
Given expression
2.1.x.z.z.z.z
here z repeats 4 times,
according to exponents z can be written as
z⁴,
2 and 1 and x are not repeated so there powers are only 1
expression is
2.1.x.z⁴ or
2.x.z⁴
Hence the expression is 2.1.x.z⁴ or 2.x.z⁴.

20 books are divided parcels, each parcel contains one fifth of the total. If a librarian wants to buy 16 books how many fifths should he take?
Answer: x=4
Step-by-step explanation:
1/5 of the total= 1 parcel= 1/5 of 20= 4
So one parcel is 4 books
Then you can set up an equation 16=4x where x = number of parcels.
4x = 16
4x/4 = 16/4
x=4
A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds,
is given by h(t) = -4.9t? + 16 + 13. How long does it take to reach maximum height? (Round your answer to three
decimal places.)
S=?
Answer:
It takes 1.633 seconds for the ball to reach maximum height.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]
In this question:
We have that the height is given by:
[tex]h(t) = -4.9t^2 + 16t + 13[/tex]
So [tex]a = -4.9, b = 16, c = 13[/tex].
The maximum height happens at the instant of time:
[tex]t_v = -\frac{b}{2a} = -\frac{16}{2(-4.9)} = \frac{16}{9.8} = 1.633[/tex]
It takes 1.633 seconds for the ball to reach maximum height.

What is the total area, in square feet, of the figure? (If possible please explain how you got your answer)
Answer:
This is going to be really long so sorry in advance :)). So i split the shape into two (so straight down).This therefore allows me to calculate the areas of both rectangles and add them together - (to give total area)
Area of A x(x^2-6)
=x^3-6x
Area of B
=(2x^3-5x^2-12x+14) (5x-14)
10x^4-28x^3-25^3-70x^2-60x^2+168x+70x-196
simplified: 10x^4-53^3-130x^2+238x-196
so add both areas to give total are:
=(x^3-6x) +(10x^4-53x^3-130x^2+238x-196)
=10x^4-52x^3-130x^2+232x-196
