(X+5)²+3x+15
This is the equation
The factors of the given equation (X+5)²+3x+15 are x(x+20)(x+2).
What do we mean by equations?An equation is made up of expressions that have the same value.A formula is a two- or more-variable equation that represents a relationship between the variables. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.The equation is: (X+5)²+3x+15
Then,(X+5)²+3x+15
x² + 25 + 3x + 15x² + 3x + 40x² + x ( + ) + 40x² + x ( 20 + 20 ) + 40x² + 20x + 20x + 40x ( x + 20 ) + 20 ( x + 2 )Factors are: x(x+20)(x+2)

A rock is thrown from the top of a ladder. The function
h(t) = -16t² + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
1. What is the initial height that the rock was thrown from?
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10)
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0

x + 3y = 17
Answer: x=2 and y=5
Step-by-step explanation:
Substitute the Y= equation for the Y in the second equation.
ie: x+3(2x+1)=17
Now all of your variables are the same and you can solve for X. You should get X=2.
Then plug 2 in for X in the first equation
ie: y=2(2)+1
Then solve for Y. You should get 5

describes the problem
The linear equation that describes the problem 72x + 150y = 5400.
What is a linear equation in mathematics?A linear equation seems to be an algebraic equation of the form y=mx+b, including only a constant and an initial (linear) component, where m is the slope, as well as b,as well as b is the y-intercept. The preceding is sometimes referred to as a "linear equation with two variables," where both x and y are the variables.
Why is it termed a linear equation?The graph of a linear equation is a straight line. Linear Equation Definition: A linear equation seems to be an algebraic equation in which each term has an exponent of one and when graphed, it always results in some kind of a straight line. it is called a 'linear equation.'
According to the given data:Tennis Club sells monthly memberships for $72.

if f is a linear function, f(k)=16 and f(-k)= -4 then what is the value of f(0)?
f(0) = ( f(k) +f(-k) ) / 2
f(0) = (16 - 4) / 2
f(0) = 12 / 2
f(0) = 6 → ANSWER
*Remember that f(0) = m(0) + n = n
If we have f(x) = mx + n, then:
f(k)= mk + n and f(-k)= -mk + n
If we add them:
f(k) + f(-k)
= mk + n -mk + n
= 2n
= 2f(0)
So we conclude that:
f(0) = [f(k) + f(-k)] / 2

Answer:
a₇ = [tex]\frac{4096}{3125}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 4 ÷ 5 = [tex]\frac{4}{5}[/tex]
r = [tex]\frac{16}{5}[/tex] ÷ 4 = [tex]\frac{4}{5}[/tex]
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = [tex]\frac{4}{5}[/tex] , thus
a₇ = 5 × [tex](\frac{4}{5}) ^{6}[/tex] = 5 × [tex]\frac{4096}{15625}[/tex] = [tex]\frac{4096}{3125}[/tex]

1.83 x 108 is how many times greater than 6.1 x 105?
Answer:
1.83 x 108 is about 3 times smaller
Step-by-step explanation:
1.83 x 108 = 197.64
6.1 x 105 = 640.5
640.5/197.64 = 3.24
Solve the system.
6x - 2y + z = -2

After Multiplying 3 with the eq. (i) we will add this to eq. (ii)
[tex] \sf 18x - 6y + 3z = - 2[/tex]
[tex] \sf2x + 3y - 3z = 11[/tex]
_______________________[tex]⇒ \sf20x - 3y = 9 \: \: .........(iv)[/tex]

_________________[tex] \sf \: 41x = 49[/tex]
[tex]⇒ \sf \: x = \frac{49}{41} [/tex]
After putting the value of x in the eq. (iii)
[tex] \sf \frac{49}{41} + 6y = 31[/tex]
[tex]⇒ \sf6y = 31 - \frac{49}{41} [/tex]
[tex] \sf \: ⇒ 6y = \frac{1271 - 49 }{41} [/tex]
[tex]⇒ \sf6y = \frac{1222}{41} [/tex]
[tex]⇒ \sf \: y = \frac{1222}{41 \times 6} [/tex]
[tex]⇒ \sf \: y = \frac{611}{123} [/tex]
After putting the value of x and y into eq. (i)
[tex] \sf6 \times \frac{49}{41} - 2 \times \frac{611}{123} + z = -2 [/tex]
[tex]⇒ \sf\frac{294}{41} - \frac{1222}{123} + 2 = - z[/tex]
[tex]⇒ \sf \frac{882 - 1222 + 246}{123} = - z[/tex]
