9x10 to the -8th power.
Since the numbers are both x10^-8, you can simply add 2 and 7. If you would rather look at it as:
0.00000007 + 0.00000002 = 0.00000009 = 10x10^-8
then you will get the same answer.
Answer:
here it is
Step-by-step explanation:
if u have any question tell me
Add the two equations together.
5y=20
y=4
Substitute that back into one of the equations.
4x+3y=6
4x+3(4)=6
4x=-6
x=-3/2
So, the solution is x=-3/2, y=4.
The answer, therefore, is D.
Hope this helps!
((2)+5)−(b/b−4)+2∗(b+3/(2)) = <span>7</span>
Perimeter = 4*(3*x+2) = 12*x +8
So 12x +8 is the answer.
