Let, numbers = x,(x+2),(x+4),(x+6)
A.T.Q,
x+x+2+x+4 = x+6+18
3x+6 = x+24
3x-x= 24-6
2x = 18
x = 9
Numbers would be 9, 11, 13, 15
For this case we have:
Be a function of the form
Where:
If we want to find f (-2), we substitute , then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:
Answer:
Answer:
Diego is 14 years old.
Sister is 19
Step-by-step explanation:
x = Diego's age
<u>x</u><u> </u><u>+</u><u> </u><u>2</u><u>4</u>
2x-9 = 2
First to get rid of the fraction we multiply each side by 2
2(2x-9) = 2((x+24)/2)
4x-18 = x+24
The we isolate x
4x-18 = x+24
<u>-x+18 -x+18</u>
<u>3x</u> = <u>42</u> Now we divide each side 3
3 3
x = 14
So Diego is 14
Now we can solve for his sister. We can use one of the two equations from earlier to do this.
Plug 14 in for x and then solve for his sister
2(14)-9
28-9
19
His sister is 19
Sadly, the cube you promised us is not shown.
IF the cube is resting on the table in the normal way ... with
two of its faces horizontal and the other four faces vertical,
then any horizontal or vertical slice is a square.
You know what's fun ? Try doing this problem with cubes of
chocolate cake, and after you make slices, look at them and
then eat them.
Answer:
4+4-8 is a doubles fact that can help you find 4+3
Step-by-step explanation:
4+3=7
4+4=8
8-1=7
By using the doubles fact 4+4 we can deduct that 4+3 = 7
