Answer:

x=0; x=-2

Step-by-step explanation:

so first you do (x+2)^2 which is x^2+2x+4

4x^2 +8x +16 = 16

Subtract 16 from both sides

4x^2 +8x = 0

factor out 4x:

4x(x+2) = 0

How do I draw a visual model using 1/6 of 18? Please help. I'm asking for my 5th grader. Thank you!

svp [43]

Answer:

Theory

Step-by-step explanation:

Take any 18 objects

For example in this case

Take 18 chocolates

$\frac{1}{6}$ means one sixth , which practically means how many groups of 6 can be formed

So, Try to divide 18 into groups of 6

Count how many such groups are formed(it will be 3)

So one sixth of 18 is 3

That is, 18 comprises of 3 groups, each group containing 6 chocolates

yanalaym [24]

Hmm, seems to multiply by 5
wait, no

first is multiply by 5
2nd is multiply by 10
3rd is multiply by 15
4th is multiply by 20
seems to be

$f(x)=x(5x)$ or $f(x)=5x^2$
the rule is square the input then multiply by 5

After travelling 2/5 of a Journey

Trava [24]

Answer:

= 100 km

Step-by-step explanation:

Total length = 5/5

Covered length = 2/5

Remaining length = 5/5 - 2/5 = 3/5

If 3/5 = 60 km

What about 5/5 = ?

= 5/5 x 60 x 5/3 (reciprical)

= 60 x 5/3

= 300/3

= 100 km

Covered distance = 100 - 60 = 40 km
