Answer:
I'm pretty sure I got this right= x = -17
Step-by-step explanation:
So, I just took away -8x from -9x to get -1
the sum looks like this now: -1+3=20.
Now, opposite of +3 is -3 so +3 cancels out -3.
Then you take that -3 and take 3 away from 20.
The sum is this now: -1x =17
Now, divide -1 from -1x and it gives you x.
Then divide -1 from 17 and it gets you to -17
The answer is then, x = -17
I hope U got that right for you!
Answer _
It is perpendicular to the equation y=15x-3.
Answer:
The area would be '15l - l²
Step-by-step explanation:
Given,
By 30 feet of wire fencing we need to make a rectangular shape,
Thus, perimeter of such rectangle = 30 feet,
We know that,
Perimeter of a rectangle = 2( length + width)
if length = l feet,
⇒ 2(l + width) = 30
⇒ 2l + 2 × width = 30
⇒ 2 × width = 30 - 2l
⇒ width = = (15-l) feet,
Now, area of the rectangle,
A = length × width
= l × (15-l)
= 15l - l²
Which is the required polynomial expression.
Note :
Polynomial expression : an expression having terms consisting coefficients and variables separated by addition, subtraction and multiplication.
Answer:
D. 7
Step-by-step explanation:
to find the median the equation is to write out all the numbers given in order from least to greatest.
4, 4, 6, 6, 7, 7, 9, 9, 10
now cross off 1 number from each side. and keep doing thaf until you find the median, aka the middle number.
4, 6, 6, 7, 7, 9, 9
cross off the first and last number that remains.
6, 6, 7, 7, 9
again until 1 number remains **that number left will be the median**
6, 7, 7
cross off first and last.
7
7 will be the median.
I hope this helps!! if you need more explanation let me know and I will supply more information.
thank you
