Answer:

I believe C, or the answer you have chosen, is correct.

Step-by-step explanation:

In this question, we add like, AKA similar, terms.

There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:

x^2

There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:

x^2 - x

We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:

x^2 - x + 6.

See how easy that was? :) Hope this helps you and you get a good grade on your test!!

Sara and Paul are on opposite sides of a building that a telephone pole fell on. The pole is leaning away from Paul at

r-ruslan [8.4K]

Answer:

a) See figure attached

b) $x = \frac{sin(124)}{sin(34)} 80.086 = 118.732 ft$

c) $h = 35 sin (59) = 30.0 ft$

So then the heigth for the building is approximately 30 ft

Step-by-step explanation:

Part a

We can see the figure attached is a illustration for the problem on this case.

Part b

For this case we can use the sin law to find the value of r first like this:

$\frac{sin(22)}{35 ft} =\frac{sin(59)}{r}$

$r= \frac{sin(59)}{sin(22)} 35 ft = 80.086ft$

Then we can use the same law in order to find the valueof x liek this:

$\frac{sin(124)}{x ft} =\frac{sin(34)}{80.086}$

$x = \frac{sin(124)}{sin(34)} 80.086 = 118.732 ft$

And that represent the distance between Sara and Paul.

Part c

For this cas we are interested on the height h on the figure attached. We can use the sine indentity in order to find it.

$sin (59) = \frac{h}{35}$

And if we solve for h we got:

$h = 35 sin (59) = 30.0 ft$

So then the heigth for the building is approximately 30 ft

Jacob is cutting yarn for a craft project. He needs pieces of yarn that are 12 inches long, but he only has a ruler marked with

lara [203]

Answer:

30.48 centimeters

Step-by-step explanation:

We know that:

2.54 cm = 1 inch

To find how many centimeters are in 12 inches, you should:

2.54 x 12 = 30.48

So Jacob’s pieces of yarn should be 30.48 centimeters long.

Hope this helps!

A student has started a lawn care business

kondaur [170]

Step-by-step explanation:

$21=per hour mowling

$17=per hour gardening

only work 16 hours per week

Goals =$275 per week

$275÷16 hours=$17.1875(Each hour in a week)

mow lawns= $17.1875 ×$12=$206.25(for 16 hours)

gardening=$17.1875 ×$17=$292.1875(for 16 hours)

mowling lawns=$275÷$21=13.0952380952(13 hours,12 minutes and 30 seconds)

Gardening =$275÷$17= $16.1764705882 (970 hours,9 minutes,80 seconds)
