1 answer:

5 0

Triple t ⇒ 3t
add the result to u ⇒ 3t + u
multiply what you have by v ⇒ (3t + u)v

Since it is instructed not to simplify, we perform the distributive property of multiplication.

(3t + u)v = 3tv + uv

Answer:

$\sqrt{6} -3\sqrt{2}$

Step-by-step explanation:

$\sqrt{150} -\sqrt{96} -\sqrt{162} +\sqrt{72}$

$=\sqrt{25\cdot6} -\sqrt{16\cdot6} -\sqrt{81\cdot2} +\sqrt{36\cdot2}$

$=\sqrt{25}\sqrt{6} -\sqrt{16}\sqrt{6} -\sqrt{81}\sqrt{2} +\sqrt{36}\sqrt{2}$

$=5\sqrt{6} -4\sqrt{6} -9\sqrt{2} +6\sqrt{2}$

$=\sqrt{6} -3\sqrt{2}$

Car A travels 702 miles on 12 gallons of gasoline car b travels 873 miles and 15 gallons of gasoline David wants to buy a car wi

Assoli18 [71]

David should buy Car A because it covers more miles in one gallon than Car B

Step-by-step explanation:

Given

Distance traveled by Car A = $d_A = 702\ miles$

Gallons used by Car A = $g_A = 12$

Distance traveled by Car B = $d_B = 873\ miles$

Gallons used by Car B = $g_B = 15$

In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons

So,

Distance traveled by Car A in one gallon = $\frac{702}{12} =58.5\ miles\ per\ gallon$

Distance traveled by Car B in one gallon = $\frac{873}{15} = 58.2\ miles\ per\ gallon$

We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon

So,

David should buy Car A because it covers more miles in one gallon than Car B

What is (-7)^3 / (-7)^4 simplified? Can you walk me through the steps?

Brilliant_brown [7]

Answer:

(-7)∧-1

Step-by-step explanation:

(-7)^3 / (-7)^4

taking each and simplifing it

-7³ = -7 x -7 x -7

(-7)∧4 = -7 x -7 x -7 x -7

(-7)^3 / (-7)^4 = (-7 x -7 x -7 ) / ( -7 x -7 x -7 x -7) = 1/-7

1/-7 ( 1/ means raise to power -1)

1/-7 = (-7)∧-1
