Your answer would be the second option, (3a - 4)(a + 3).

We can see that this is the correct answer as if we expand it using FOIL, we get 3a² + 5a - 12:

(3a × a) + (3a × 3) + (-4 × a) + (-4 × 3) = 3a² + 9a - 4a - 12
= 3a² + 5a - 12.

I hope this helps!

It takes 2 hours for a boat to travel 28 miles downstream.The same boat can travel 18 miles upstream in 3 hours .Find the rate o
UNO [17]

Answer:

  4 mph

Step-by-step explanation:

The speed downstream is (28 mi)/(2 h) = 14 mph.

The speed upstream is (18 mi)/(3 h) = 6 mph.

The speed of the current is half the difference of these:

  (14 mph -6 mph)/2 = 4 mph

_____

The current adds to the downstream speed and subtracts from the upstream speed, so the difference of those speeds is twice the current's speed.

How do you solve 2x-2y+5=0 for x and then also for y
Sedbober [7]
Solving for 'y'

2x - 2y + 5 = 0

Add 2y on both sides

2x + 5 = 2y

Divide by 2 on both sides

y = x + 5/2
y = x + 2.5

Solving for 'x'

2x - 2y + 5 = 0

Subtract 2x on both sides.

-2y + 5 = -2x

Divide 2x on both sides

x = y - 5/2
x = y - 2.5

Find the missing x value for for question 14
zloy xaker [14]

Answer:

x=12 but who knows maybe

Step-by-step explanation:

if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.
