Answer:
f(-3)= 15
Step-by-step explanation:
f(-3) means x is equal to -3
-3 squared - 2(-3)
-3*-3 -2(-3)
*Negative multiplied by a negative equals a positive
9+6= 15
f(-3)= 15
Hope this helps!
No. To solve the equation it needs to be set to 0.
1. x^2 +7x = 0
Then the GCF needs to be found
2. x(x+7) = 0
Set each to 0
3. x= 0 or x+7=0
Solve for x
4. x=0 or x=-7
Answer:
(Wind speed: 81,000) and (Rate of the jet in still air: 11,820)
Step-by-step explanation:
We know that 5040 times 8 is 40320.
And 6780 times 6 is 40680.
Then, add them together and the rate of the wind is 81,000.
The rate of the jet, add them (6780 plus 5040) and you'' get 11,580.
5(2x + 6)
10x + 30
divide 2 on both
5x + 15
divide 5 on both
x + 3
