We simply need to plug in x = 4 into x² + 2x
So plugging in x = 4, we get:
4² + 2(4)
Simplifying it, we get:
16 + 2(4)
16 + 8
24
When x = 4, x² + 2x will equal 24.
Answer: On a coordinate plane, 5 points are plotted. The points are (1, 3), (2, 6), (3, 12), (4, 24), (5, 48).
Step-by-step explanation:
When x=1, f(x)=3. So, it passes through (1,3).
So, everything is eliminated except for option (4).
Answer:
(x - 3) (x + 4)
Step-by-step explanation:
roots are -4 and 3
then
f = (x + 4)(x - 3)
The expanded binomial is 2x^3+3y^2=7
<u>Step-by-step explanation</u>:
- The binomial is not shown in correct expansion. It is written in the wrong format. There is a general format for the binomial expansion.
- The first term should have the highest power. So 2x power 3 will come first. The second term will have power lesser than the first term.
- So in the second term, 3y^2 will be placed. After that, the equal to = operator will be placed. Finally, the value of the expression will be placed.
- So the expanded correct form is 2x^3+3y^2=7
