Okay, so...
length = x+2
width = 2x-5

Multiply these
x+2(2x-5)
x + 4x - 10
5x - 10 = 56

5x - 10 = 56
+ 10 + 10

5x = 66

x = 11.20

:D

Answer:

NPV = $ 17,200,000

Step-by-step explanation:

Total expenditures = $ 11,000,000

Net cash inflow = $ 3,000,000 per year

total duration of cash inflow = 9 years

Thus, total cash inflow = $ 3,000,000 per year × 9 years = $ 27,000,000

salvage value = $ 1.2 million = $ 1,200,000

NPV = Salvage value + total cash flow - Expenditures

on substituting the values, we get

NPV = $ 1,200,000 + $ 27,000,000 - $ 11,000,000

or

NPV = $ 17,200,000

A line with a slope of -1 passes through the point (0,0). What is its equation in slope-intercept form? Please answer quickly.

rusak2 [61]

Answer:

y = -x

Step-by-step explanation:

The line has a slope of -1 and it passes through point (0,0)

Taking another point (x,y) on the line;

Slope = change in y ÷ change in x

For our case; slope = $\frac{y - 0}{x - 0} = -1$

Cross multiplying this gives;

y = -x

Komok [63]

Remember
$x^{ \frac{m}{n} }= \sqrt[n]{x^m}$

so
$x^{ \frac{1}{2} }= \sqrt[2]{x^1}$ or √x

Need help with this work sheet

Lesechka [4]

Answer:

its alot to explain but i will try to make it as simple as possible

Step-by-step explanation:

your first goal is to make each problem into the form ax^2+bx+c=0

number 1, 2, 7 and 8 is already done for you

now all you have to do is plug in each number in the standard form into the quadtratic formula.

basically at this point you can just use your calculator to do the rest of the work. dont forget parentheses so it doesnt get confused...

or you can perform the algebraic work.. its all just a matter of plugging in the right numbers into the quadratic formula...

cant really do the work for you since im on my phone. but yeah all you need to do step one is transform each problem into ax^2+bx+c=0 form

then step 2, plug in each number in to the quadtratic formula. from there calculate using basic algebraic rules
