Remember
x-(-y) means x+y since minusing a negative cancels

-3z^7+5z^7
addthe coeficients
one way to show is undistribute
-3z^7+5z^7=(z^7)(-3+5)=(z^7)(2)=2z^7

answer is 2z^7

A seed Company planted a floral mosaic of a national flag. The perimeter of the flags 540 feet. Determine the flags length and w
stiv31 [10]

Answer:

Length of the flag is 190 feet and width of the flag is 80 feet.

Step-by-step explanation:

Given:

Perimeter of the flag = 540 feet

We need to find the length and width of the flag.

Let the length of flag be 'l'.

Let the width of the flag be 'w'.

Now given:

length is 110 feet greater than the width

Length of the flag l = 110+w

Now we know that,

Flag is in rectangular shape.

So Perimeter of rectangle is given by 2 times sum of length and width.

framing in equation form we get;

2(l+w) =540

Now dividing both side by 2 we get;

\frac{2}{2}(l+w)=\frac{540}{2}\\\\l+w =270

Now Substituting the value of 'l' in above equation we get;

110+w+w=270\\\\110+2w=270

Subtracting both side by 110 we get;

110+2w-110=270-110\\\\2w= 160

Dividing both side by 2 we get;

\frac{2w}{2}=\frac{160}{2}\\\\w=80\ ft

Width = 80 feet

Length l =110+w =110+80 =190 \ ft

Hence Length of the flag is 190 feet and width of the flag is 80 feet.

I need help please thanks
strojnjashka [21]

Answer:

y = 1/2x + 0

You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.

There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help
