Step-by-step explanation:
Answer:
(x+7)(x-4)
Step-by-step explanation:
(x^2-4x)+(7x-28)
=x(x-4)+7(x-4)
=(x+7)(x-4)
The correct answer for the exercise shown above is the first option and the las option, which are:
<span>y = 3x + 20
3x - y = -20
</span>
The explanation is shown below:
1. You have the folllowing expression given in the problem above:
y-2=3(x+6)
2. If you solve it for y, you have:
y-2=3x+18
y=3x+18+2
y=3x+20
3. And if you move the variables to the left member, you have:
3x-y=-20
Therefore, as you can see, the correct answer are the options mentioned above.
Answer:
50.27
Step-by-step explanation:
perimeter= length of arc + 2r= 14.28
length of arc= rx where x is the angle which is pi/2
radius =4
area= pi* r^2= 50.27
I mean, this isn't a question but its true?
