Answer:
-5x^3 -10x^2
Step-by-step explanation:
(x^2 *(x+2))(-5)
Apply the distributive property
(x^2 x + x^2*2)(-5)
Multiply x^2 by x by adding exponents
(x^3+x^2 *2)(-5)
Apply the distributive property
(x^3 + 2x^2)(-5)
-5x^3 -10x^2
I believe the answer to this is the third box
Step-by-step explanation:
you are "hiding" some more information (like how much they made together).
without that we cannot calculate the actual values.
all I can do is set up the equations expressing the given relations between the parts of the total :
a = amount Alberto made
b = amount Benjamin made
c = amount Carlota made
b = 3×a
c = 2×b = 2× 3×a = 6×a
that's it.
your see ? now we need something that "ties" all 3 together, an equation of all 3 variables, where we can use the first 2 equations (by substitution) and then solve for the remaining third variable.
and that is missing.
if it is something like "together they made x", then we would have
a + b + c = x
a + 3a + 6a = x
10a = x
a = x/10
b and c we get then from the first 2 equations by simply using the calculated value of a :
b = 3×(x/10) = 3x/10
c = 6×(x/10) = 6x/10 = 3x/5
5 whole and 1/6 hope it help you
Answer:
82209,96 miles
Step-by-step explanation:
1. 5,7 x 102 = 581,4 miles/hour
And
1,4 x 101 = 141,4 hours
2. 141,4 (hours) x 581,4 (miles) ÷ 1 (hour) = 82209,96 miles
It's the rule of three...
I hope it helped you!
