Hello.
The are answer is 4 or 3
<span>
3^2 = 7(3) - 12
9 = 21 - 12
9 = 9
</span>4^2 = 7(4) - 12
16 = 28 - 12
16 = 16
Have a nice day
Answer:
x = 4.
Step-by-step explanation:
These are exterior alternate angles which are congruent.
So 21x + 6 = 90
21x = 84
x = 4.

you need to add all numerators, same denominator
Answer:
Maximum is 4
Step-by-step explanation:
M(x) is quadratic function, so we need to fin maximum.
m(x)=-x(x-4)
m(x)=-x^2+4x
To find a maximum we need to find m’
M’(x)=-2x+4
M’(x)=0 if x=2
The maximum is in the point x=2
M(2)=-2(2-4)=4
