Answer:

Step-by-step explanation:

y= 40x + 50

y= 35x + 100

y= 40x + 50 = 35x + 100

40x - 35x = 100 - 50

5x = 50

x = 50/5

x = 10

y = 40 * 10 + 50 = 450

so the first answer is the correct one

Answer:

The area of the square lawn is $784\ m^2$

Step-by-step explanation:

Part 7)

Let

x ----> the length side of the square lawn in meters

we know that

The area of the path is equal to

$A=(x+2+2)^2-x^2$

$A=(x+4)^2-x^2$ ----> equation A

$A=240\ m^2$ ----> equation B

$240=(x+4)^2-x^2$

Solve for x

$240=(x^2+8x+16)-x^2$

$240=8x+16$

$8x=240-16$

$8x=224$

$x=28\ m$

The area of the square lawn is

$A=x^2$

substitute the value of x

$A=28^2=784\ m^2$

2 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!

Ivanshal [37]

Answer:

This series is divergent

Step-by-step explanation:

we are given a series

Firstly, we will find nth term

Numerator:

3, 4, 5,...

so, nth term will be

$a_n=n+3$

Denominator:

4,5,6,....

so, nth term will be

$b_n=n+4$

so, we can find it's nth term as

$c_n=\frac{n+3}{n+4}$

we can use divergent test

$\lim_{n \to \infty} c_n=\lim_{n \to \infty} \frac{n+3}{n+4}$

we can divide top and bottom by n

$\lim_{n \to \infty} c_n= \lim_{n \to \infty} \frac{n/n+3/n}{n/n+4/n}$

$\lim_{n \to \infty} c_n= \lim_{n \to \infty} \frac{1+3/n}{1+4/n}$

now, we can plug n=inf

$\lim_{n \to \infty} c_n= \frac{1+0}{1+0}$

$\lim_{n \to \infty} c_n=1$

Since, it is non-zero value

so, this series is divergent

For any two integers a and b, (a + b)² = a² + b²

kozerog [31]

Answer:

wrong

Step-by-step explanation:

(a+b)^2=(a+b)(a+b)

=a(a+b)b(a+b)

=a^2+ab+ab+b^2

=a^2+2ab+b^2

i hope it helps you
