Answer:

4) Alternate Interior angles 5) Parallel lines property.

Step-by-step explanation:

The question is asking us to Complete the statements to prove that line AB ⩭ to line CD and line BC ⩭ to line AD.

In statement 4 .∠CAB is congruent to ∠ACD as AB is parallel to CD and ∠BCA is congruent to∠CAD as AD is parallel to BC and these are Alternate interior angles to the parallel lines .

In statement 5.m∠CAB =∠ACD and ∠BCA = ∠CAD as by property of parallel lines Alternate interior angles are equal.

If a canoe travels with a speed of A mph for 3 hours, and then with a speed of B mph for the rest of the journey, how long does

Mandarinka [93]

Answer:

t = (C - 3*A)/B + 3

Step-by-step explanation:

Given in the question that,

the speed with which canoe travelled for first 3 hours = A

the speed with which he travelled for any and all time thereafter = B

As we do not know the values of A, B, or C, so the answer will be an expression for C in terms of A and B.

<h3>Formula to use</h3>

distance = speed x time

C = A*3 + B*(t-3)

Rearranging and solving for t

C - (A*3) = B*(t-3)

C - (A*3) = Bt - B3

C - (A*3) + B3 = Bt

t = C - (A*3) + B3 / B

t = (C - 3*A)/B + 3

PLEASE ANSWER QUICKLY

Olegator [25]

Answer:

x=3

Step-by-step explanation:

Set equations equal to each other:

$x^3-3x^2+2=x^2-6x+11$

Subtract two from both sides

$x^3-3x^2=x^2-6x+9$
Factor out x^2 from the left side

$x^2(x-3)=x^2-6x+9$

Factor the right side, look for two factors of 9, which add to -6, which is just -3 and-3

$x^2(x-3) = (x-3)(x-3)$

So as you can see here, we have both sides in factored form, and both have a factor of (x-3) on both sides, and if one of the factors is zero, then the entire thing becomes zero, since 0 * anything= zero.

this means a solution would be at x=3, since it makes the right side 0 * 0 = 0, and the left side (3)^2 * 0 = 0

It's important to notice this, since had we divided by x-3 to make the equation a quadratic, we would've excluded this real solution, because when dividing by x-3 the solution x=3 makes it 0, so we would've been dividing by zero.

So one of the real solutions is at x=3
